Thanks for playing! I'm glad you liked the overall look of the game. A combination of cc0 assets and some homemade ones. The lighting is definitely a bit rough, we probably should have spent a little more time on that at the start. For the final room, there is a few bookshelves next to each other and that's related to making it to the top most floor. It's a bit of a puzzle with no introduction but we wanted to see how people handled it so we threw it in at the very end.
