While a bit short this game was so much fun and so beautiful. I enjoyed the ending I got but look forward to playing again and seeing the other

okay so it looks like there is only one ending to the game, but still pretty fun


she,,, knew,,,


Still sad I couldn't get ending 1 but still such a beautiful game. 


My completionist self is going crazy. PLEASE, someone tell me how to get Ending 1 - it's killing me


such a weird game to play in 2020 since a similar pandemic is happening lol


so so informative!! i learned a lot of stuff and your art is amazing :)) i haven't finished the game yet, tho !!

Good game, but couldn't get ending one no matter what I tried. Not sure how other people managed to get it. Overall, enjoyable. Art is amazing and the interactive play is nice.

very glitchy, but so educational and lovely!



coronavirus jokes aside, this was an excellent game. i learned more about tuberculosis than i ever cared to know! amazing art (though that's not surprising) and great choice of music. encountered quite a few bugs, but nothing that ruined the experience.


Corona, corona, corona, corooooona...

One, wash your hands.

Two, don't touch me.

Three, wear a mask.

Four, don't touch me,


Don't touch me.


What a coincidence but please make more games, I'm a big fan of your work hehe 


year 2020 hMMm


oMg, iT iS sUch A cOinCideNcEeeE


man, this game is so ironic but the fact i can't get all of the bacteria at the end is so frustrating! 


Uh Angela... did you actually see this coming? xDDD

uhhh O_O

ikr .-.

THIS GAME IS AMAZING but, I can’t save…


I just wanted to stop by now that I have an itch account and say I love this game! Edutainment is the best and this not only does those two things, it also forces you to make choices that direct a part of the world's course in complicated ways you don't always expect. I played this over a year ago and I still feel like I played it yesterday. That's how memorable this game is. 


Dang- This was made before and it mentioned 2020, now this is giving me the heeby jeebies

Dude same...I got the chills when the year came up in the game.


Corona Virus?

certeza heuheu


Lovely art and I learned a lot about biology in a non overhwhelming way

I kept losing the cursor because it's too small and dark especially on the dark text background though

This game is great. Relaxing and educational.

Such a great game. Got stuck, then realized i was just dumb. ^_^

Really appreciate the little game experience by learning at same time.  Can't find the way to finish the game though

How do you manipulate the bacteria?


The game is too glitchy for me to really play through :(

It freezes up a lot and at one point layered some of the inside the body pictures over the setting of the apartment


maybe try setting the graphics quality to simple. if you have an old computer and/or a mac, (like me) it'll be a lot slower

How can i manupilate the granuloma?


lol its 2019... anyone else scared??? haven't played yet, but I'm excited!!!!!


it's 2020


how do you get ending one? Also, i hate biology, but i LOVED learning about it in this visual novel/game. I'd pass my bio class if my studying sheets came in this type of format >w< Please continue to make more visual novels like this that take thinking/learning ,yet aren't overwhelming!!! 

k first things first, this game's an emotional rollercoaster that I rly enjoyed but i'm still stuck because I can't manage to get the other ending :(( could someone help me out?


This game is just brilliant! I like the gameplay and the storyline. But the ending is way too sad for me. It says: even magic can't help you resque the one you love, so all you have is a little hope. This is distressing, because this is reality.

Also, I've encountered the same bug L1ght5h0w wrote about a year ago: I came to grandma before visiting Red's mother and was unable to return to the Metro.


I didn't get a sad ending, but a happy one. i'm unable to unlock the other one, tho.

I got ending where Red's biotechnically skilled friend will recreate Red's grandmas brains, not sure if this is happy ending or not.


Hi so far the game is good but the left and right edges are flashing pretty often and it causes a slight headache. Can you fix it?

may you please fix the lights glitch, that matter is serious others with epilepsy


Can someone explain how to get the first ending?
