I got a bit late to vote for the jam, but I still wanted to give my feedback ^^
I actually was pretty invested in the concept. Slowly get pieces of information through your own effort is really cool! I have to say, I felt a bit silly sometimes, but I am glad the game doesn't punish you for skipping riddles. I think they are well though out, although a bit hard (the second maze drove me nuts hahaha)
The good ending is very good, as it makes it all make sense, and I think it hurt you a bit that it was not implied in a way people would actively look for it. I mean, I didn't know there was one until I saw comments about it and, without it, the story lacks a proper ending.
I am eager to see what else you got prepared :3
