The visuals are awesome! Especially the drawn parts like the character and the floor tile. The animated floor effect was also pretty neat.
I had a bit of a hard time solving some of the puzzles. I think it's because there is no minimap, so it's running around a lot and remembering stuff. With a map and clear overview over what is going on the puzzles could be even more complex and still enjoyable.
Great execution and over overall a really cool and fun game! Great job!
