I really liked the feel of this game, the visuals, presentation everything was ++. The only gripe, which I think was the case for some of the other comments here, is the final puzzle. I had to search here for hints, and even with those it took me a good while to find the solutions. I recorded my play session, so hopefully I can upload that soon since I talk more about it there, but I think with a few more limitations in the final room, for example, if there was say a green carpet or stone near the door opened by the green book, and then only one green book in the library to help the player make the connection, that would be all it takes to make that last level flow that much better.
Still, thats a small thing workable by play testing, apart from that great game feel and for 48 hours GREAT WORK on the visuals and layout.
If you have time, would love to hear what you think of my game; https://itch.io/jam/gmtk-2019/rate/461074
