Mycopsychosys
A downloadable game for Windows, macOS, Linux, and Android
In this game, you will experience the horrors of a sporestorm, a new weather phenomenon that is becoming too common in the whole country of Spain. Heavy clouds that contain Mycopsychosys spores are approaching your area. If you want to survive, you have to stay inside your home and closely follow the PCD (plague control department) issued rules.
Meet our small but charismatic cast of characters, engage and take care of them.
To enhance the experience and to help the player survive, a web page has been created by the PCD containing crucial information about the spores, the infection and about those who fall ill from it:
In case you don't have an active internet connection, we've also included the information inside the "Survivor manual" folder.
This game was originally created for the Spooktober 2023 but with all the love from the community it evolved to something more. Something unique. Not only a story but a whole universe you can explore.
There are currently two versions of the game available:
FIRST VERSION [FREE]
- Features the 3 original characters, with the story and graphics preserved exactly as they were on launch day.
- Completely free.
- Includes 5 endings
If you want to see how it all started, this is the perfect version for you.
REMASTERED VERSION [PAID]
- A much larger and refined version of the game, with several upgrades:
- Redrawn characters
- New backgrounds
- Added animations
- Expanded story and deeper lore
- Introduces 2 new characters.
- Adds a brand-new ending, bringing the total to 6 endings.
This is the recommended version if you want the full experience and would like to support the project. If you enjoyed the original or want to dive deeper into the world, this one’s for you.
Game in:
- English
- Español / Spanish
- Català / Catalan
- Death
- Mild Gore
- Foul language
- Biological horror

wow i would love to help in dev..
Hi Delta Cat Studio, I'd love to help you bring mycopsychosys to Arabic gamers If you're interested in an Arabic translation, please let me know your email or contact me at urbgamesplatform@gmail.com
Tuff game
Faz a versão em português Brasil por favor
Hell of a game. I'm very much looking forward to the next game.
Can you make it play on browser PLEASE
I love this game so much. The art style, characters, and the Lore I love it.
Question for creator/'s:
-If you are able to answer; What's the canon age and height of the Characters? Do they have particular personalities?
-What inspired you to make this game?
-Are you able to tell us any canons about characters? Like, do they all love to break into our home (just joking).
-Did Noah's dad got infected by the spores? - Asking for a friend that totally isn't me trying to adopt poor gremlin and spoil him rotten.
-Will there ever be a fandom page about Mycopsychosys?
(Thank you if you see this. The game is a masterpiece. Keep it like that.)
Thank you so much for your interest for our game! We love to hear players liked our story, characters and game in general( ⸝⸝´ ᵕ `⸝⸝)
As for the questions, we have answered a few of them (and more!) on our Discord Community if you want to take a look. There are so many facts about them there! But still let me quick answer them here:
1. What's the canon age and height of the Characters? Do they have particular personalities?
⭑Onna: Around 168cm [5'6'']
⭑Hugo: Around 175cm [5'9'']
⭑Ray: Around 185cm [6'1'']
⭑Noah: Around 159cm [5'3'']
⭑Silvia: Around 177cm [5'10'']
As for the personalities, ignoring the infection status, they do all have different and vibrant personalities. I would say Onna has the brightest personality of all, compared to Ray who is more introverted than anyone.
2.What inspired you to make this game?
There are a LOT of series, books, games and stories in general that inspired us to make the game. The first one is obviously the real Cordyceps fungus. The curious way of infecting ants fascinated us and really made us question what would really happen if that fungus infected people.
The game "The Last of Us" also uses this fungus as an inspiration, but they use it more like a "Zombie Virus" type.
I think it's also worth mentioning the anime "Parasyte" , "The Summer Hikaru Died" and, of course, the series of "Doppelgänger"
3. Are you able to tell us any canons about characters? Like, do they all love to break into our home (just joking).
Noah probably loves to break into houses---- haha
But as for any canon there could be a lot of them! There are a lot of stories of them (and theories) on the Discord Server and, I can tell you, on our next games Mycopsychosys:Project Jupiter there will be a lot of information of the characters Hugo, Ray and Silvia.
4. Did Noah's dad got infected by the spores?
That's a very interesting question actually--- (👁ˋ _ ˊ 👁) but that's up to you! Maybe he is??
5. Will there ever be a fandom page about Mycopsychosys?
If you are referring to the usual fandom wiki page I know two of them:
-https://villains.fandom.com/wiki/Hosts_(Mycopsychosys)
-https://vsbattles.fandom.com/wiki/Mycopsychosys
I hope I've answered your questions! If you have any further questions, we can answer them in the server's FAQ section!
Once again, thank you so much for your enthusiasm!ദ്ദി(｡•̀ ,<)~✩‧₊
Thank you so much for your answers DeltaCatStudio.
(but just the age is missing but I don't mind. I've already have few headcannon Noah is around teen years(15/16/17 years old), Hugo is 21 years old, Onna is around 18 years old. Correct me if I'm off. Gonna go and join Discord server>:3)
Now I can go and adopt the little gremlin child(Noah) Mhahah >:3
Will you ever release merch for these characters? I'd LOVE to support you more!
Thank you so much for your interest for our game!( ⸝⸝´ ᵕ `⸝⸝)
We have a sticker pack that we sell at the few events we attend, but it's not available for international sale... For the moment, we're putting all our energy into working on the Project Jupiter prequel!ദ്ദി(,,>ヮ<,,)
We hope to be able to make more merch in the future!
I cannot get enough of it! I hope to see more games like these soon. You can check it down here! ♥️🧸🌨️

you oughta check your settings for downloading/installing "unknown" programs in your security/browser settings:) you can choose to allow them or give a prompt first before letting you decide!

Absolutely love this game and the community, glad to be a part of something so great and be able to see the team progress with other projects too. Y'all are amazing people. ♡
I was wondering since I bought the game here is there any way I can get the updated version or do i have to rebuy it on steam because i only own a macbook and the updated version on steam only runs windows,
Hi! First of all thank you so much for your interest ♡
We are currently still working to release the Myco's IOs updated version (it will be for Itch.io and Steam). If you only own a macbook I recommend waiting and keeping up for that version to be available.ദ്ദി≽(•⩊ •マ≼
Muchas gracias por jugar a nuestro juego ฅ^>⩊<^ ฅ! Nos encanta ver a jugadores disfrutándolo /ᐠ > ˕ <マ ₊˚⊹♡
Estamos trabajando en la segunda parte Mycopsychosys: Project Jupiter.. quizás allí hayan algunas respuestas de la trama de Silvia... ദ്ദി ◉w◉)✧
I just downloaded the demo version since I can't buy the game
I doubt it'll get my real name considering I don't really have much of my real information in my pc
Edit: nvm, the officer lady isn't in the demo game apparently
CAT STUDIO PLEASE SEE THIS-I LOVE THIS GAME SO MUCH THE CHARACTERS (especially Noah) ARE SO CUUUTE! MAY U PLEASE GIVE NOAHS DAD THE SPORES THEN LET ME ADOPT NOAH?.
(this game is so peak ❤️)
Glad you liked our game!
Hi! Is there a way to stream it without the worry of the part where it says your full name? I was watching a playthrough and i really want to get it to play on stream but that worries me a bit. should i work around just being careful for that part and switching my stream screen for that interaction?
Hey! It's basically just your PC's username so you can try to change that or just be carefull when interacting with her. Whatever is easier for you. She won't display any other personal information.
Hi, one question, will the remastered version be available for Android or only for Windows? I want to buy it, but I don't have a computer. By the way, beautiful game and characters. ❤️
Hello! Thank you for contacting us ♡♡
We plan on releasing it for Android in the future! Sadly we can't tell when will be the exact date since we are still working with Mycopsychosys Project Jupiter and fixing some small bugs from Remastered... But we will make sure to announce it!=(๑✪ᆺ✪๑)= ∫
I understand, thanks for answering me. ✨ I'll be on the lookout for future updates.
Wooowowow I loved this game! The animations/art were cool, the story is interesting and I really liked saving everyone and then going back to get them infected lol. I saw there was mention of more backstory for Hugo in another project and that would be awesome, especially considering he was my favorite lol. Can't wait to see what you develop next!Waah!! Thank you so much =/ᐠ> ⸝⸝⸝<マ=!!♡♡
We really appreciate your kind words and your video♡ Love to watch players enjoying our game !
You should add more about the backstory of Hugo looks interesting why Sylvia was searching for Hugo and the interactions with Hugo and Ray
Hi! We are currently working on Mycopsychosys: Project Jupiter where you follow the steps of Hugo on the Plague Control Department!
If you like to theorise we also have our beautiful community on Discord/ᐠ > ˕ <マ ₊˚⊹♡
Came here because of Manlybadasshero and I love the art style, I can't wait to see what else y'all create, keep up making god tier games
Lol SAME, the moment he Saved before letting the Basement guy in I realized it was a Itch.io game...
The added animations made the characters more life-like (and terrifying when infected and threatening your life).
Onna has adorable expressions and ooooohh, the multiple-choice, alternate appearances for her, her window animations, and the phone call were all so horrifyingly beautiful.
I love that Hugo actually reacts to Infected forcing entry/you letting them in now. I also enjoy that he has added new dialogue while inside the house (ironically in the original game, you spoke with him more when you didn't let him in) and that he has some secret lore involving government agents?
Noah has a cool design and I'm charmed by their delinquent personality! Sadly, they have Hugo 1.0 syndrome where not letting them into the house (immediately) actually lets you learn more about them. I wish they spoke more with you or Hugo. Like they do talk to Hugo once when you let them in, again when you offer soda at the end, and of course during the actual ending.
I did understand that the only reason they explain themselves is because they will die if they can't persuade you. So they don't have to be talkative once you've let them in. You can't get Noah or Hugo's endings without interrogating them outside which, though uncomfortable, actually lets you connect with them more than just letting them in immediately. Haha, I suppose I'm just greedy for more interactions/learn more about everyone's pasts.
It was really heartwarming that Hugo is protective of Noah if an Infected enters the house though. Oh, if only I could be a guardian angel watching over the two of them long after they've left my game screen and walked home together.
I'm glad there's an actual good ending you can get now and the situation isn't completely bleak and hopeless. You can even "pick" who you want to spend your ending with!
We're happy to hear you enjoyed the updated version of our game! We saw many people wanted to see a more optimistic ending, and I don't blame you. I like drama but I also prefer happy endings ദ്ദി/ᐠ｡‸｡ᐟ\
hello, ive purchased the game and downloaded it, how can I open and play the game?
Hi! Thank you for reaching for us
If it's your first time dowloading a game for itch.io it works just like a normal file!
this game is so peak im in love with hugo
i love Onnas character design so much, keep up the great work and i cant wait for project jupiter!
I'm just saying. If Silvia knocked on MY door, I'm not surviving the sporestorm.
Got this game on steam and absolutely love it! Can't wait for the Project Jupiter. Ray and Silvia are my favorites
But I'm going insane trying to get "Second time's charm" achievement...
Hello! We're glad to hear you enjoyed the game, and thank you for your support.
We've confirmed that the achievement you mentioned is indeed bugged, which is why it can't be unlocked at the moment. We'll be releasing a patch soon to fix this issue. We're so sorry for the inconvenience. (₌ ᵕ̣̣̣̣̣ ᆽ ᵕ̣̣̣̣̣₌)
