Had a bug occur to me during my play through. Kind of killed the mood I think hahaha. Was trying to enjoy this the best I could! I'm not big on hospitals,doctors, or failing health. I'm a big fan of visual novels though!

aw sorry, yeah, maybe I shouldn't have posted this to itchio? lolol it was for academia. thanks for trying!

Went ahead and finished it up...Dope game.

Yay awesome!


Accidentally went to Grandma's before bringing the stuff to Mom. On the screen in front of Grandma's house, I couldn't click the left to go back to the bus.

hmmm I'll look into that...

aa, i tried it but i can't seem to get to ending 1? do I have to be faster or make different dialogue choices? sos D: 

Gave it a go...


Someone help mee on the grandma part, where one of the red pill is stuck because of the purple ball

D: ??? can you explain which section? (brain, etc) The brain is a bit difficult to strategize.

Hey thanks for the quick reply :)))) 


Im stuck in this part, I can't get the bacteria because of the calcified granumola (purple ball)

ah. you have to strategize. Aka you have to manipulate the bacteria so it moves the granuloma by itself, then you can destroy it. hope that helps.

Owh yaaa I got it thankss soo much, I feel so dumb that i took so long to try and figure it out :p

how do you manipulate the bacteria T-T

great game really enjoyed it here is my playthrough 

Sometimes I met a glitch after the progress of TBC bacteria in potential patient's lungs and when I want to scan Red's own body, but overall it is a unique way in explaining a health problem  that normally comes as heavy topic even for the doctors. The nature of the story is written beautifully and the scene is captivating, with a distinctive art style that can only expected from this creator ^^

ah! I made it so long ago that I don't know how to debug it >< Hopefully you made it to the ending alright. Thanks so much Sora Album and I hope you found this heavy topic enjoyable.

Oh, I see... no problem then, I pretty much enjoy it; like a nice review of memories in medical studies I had long time ago >w<

Although.... I still don't get Ending 2... I always end up in Ending 1 :'D

(Edited 1 time)

haha that's great ^^ hm.. omg.. I think I integrated Ending 2 in but I may have not -sweats- I'll check asap

ok yeah ending 2 is there, but you have to seriously f up to get it.

LOOOOOVE the visuals again!  A big fan of the artist! Couldn't help but play the game. Definitely thinking of making a series for this!

thanks Frosted Fricks!! :D 

Whoaa this looks so interesting??? Brb- 

I get it(
