If you are ever interested in coming back to this game and improving on it, I found the following bugs:
I also ran into a visual glitch where my game screen flickered from the gameplay to a black screen very quickly. It started at the word jumble game. In another playthrough, this occurred when I selected the book in the top left multiple times. My guess is that it is a problem with switching between menus or screens.
The continue button on the main menu is a bit broken. Pressing it lets you spawn in with all of the medals and knowledge you've learned, along with all the rooms you have unlocked, but the game forces you to go through all of the introductory dialogue and tutorial prompts, and it respawns every clickable item in every room.
I like your games and your commitment to education, so I would love to see this game in an improved state! :)
