Really cute game! (I am super biased toward dragons and kobolds, though)
I enjoyed the puzzles, they were very neat. I did discover a bug where I could get stuck in a door when I closed it, and then I would have to reset back to the main menu, which wasn't too great!
I did also struggle with locking the treasure room at the first level. I think you needed to have the key? I'm not too sure, though - and it did seem like you couldn't pick up the key anymore after placing it down.
Still, I love the premise of the game and the art is really good! definitely not cause I'm furry trash,,,
