First of all, the character designs are gorgeous! Love how 2200 and 0 looked and all of the artworks are brilliant. The lazy sofa one is probably the best, but I also like the gun point one. Music is also great, and it complements the game well. The story is really nice, and there's a huge amount of dialogue too! I never expected how the game would suddenly turn into a Phoenix Wright game, where you present evidence to rebut 0's claims. Kind of unique in the jam if you ask me. It may be me not paying too much attention, but the choices were quite hard, and it took me a while to get it right. For some unknown reason, the first choice took me the longest to solve, which is a bit strange.
For a nitpick, I would say it would be nicer if there were a prompt to move on to the next room, as for my playthrough in the fourth gun room, I went straight to the bed first, and missed the dialogue about the fish tank. This would probably happen for the other rooms as well if I examine the gun first, and that would definitely break the game, where the player doesn't even have enough information to beat the game.
Anyway, I think this is a really nice game! Well done!
