I reached day 0+2-2 with no idea what was going on but loved every second of it. I believe I left it at hide and seek with catfood.
I also found a few typos in the beginning and dialogue that didn't fit the screen when triangle is talking to cube root after talking about shapes.
I would recommend that you move the game to Renpy or other engine instead. Kocho was laggy and was quite hard to even start cause it would give me a black every time i would preview the game.
Really loved it and had a good time!!
I wish you all the best!
