I've come to play not feel. That was a very good way of demonstrating illness. I loved it.
I noticed some bugs, where the "Go to sleep" button subtitles stay even tho I click on continue, The gibberish subtitles are stuck like this and even when I'm getting out of the game and returning it stays there. Theres also a white square at the top of the screen at stage 3.
I liked that in the second stage you inverted the controls. Thought its a bug at the start. I think it's worth building upon that. At the third stage, the controls are not inverted anymore and it's a shame, I suggest messing with them even more at that stage.
Overall I liked it, good job!
