I thoroughly enjoyed this game! The game stays focused on the key aspects as you navigate each room, attempting to discern the correct answer. I did appreciate being able to use repetition to solve some of the harder rooms, as there were a few that were partially up to chance. I really enjoyed the art style, characters, and music for this one. It created a very enjoyable atmosphere.
I generally didn't have any issues except at the very end. I was stuck on the game screen, unable to exit, change tabs, or recover my cursor for some reason. The only way I was able to quit was by using the Tab key to refresh the page.
Besides that, excellent entry!
