Playing a game made entirely in C is interesting. It reminds me of when I had to make a text adventure game in assembly for one of my classes. Making this kind of game can be a pain, especially when the player has to type in very specific things.
I cheated and look at the source code to find out who the character was, and then realized I could've just asked her who she was. I like the concept of having to guess what character it is based on given information, it is a fun test of Touhou knowledge for the Touhou-themed jam, and getting punished for guessing wrong is pretty fun. I think a line saying something like "maybe i should ask her some questions" would be helpful, since it didn't cross my mind that I could've asked her more questions and I missed out on all the hints, causing me to cheat like some scoundrel.
