Love the art and sounds. Some music would help, especially since theres pause music but not in game music. The areas were cool, but the world didn't feel super interconnected and the game was very linear.
I really like the approach to rooms, and the map was nice, but I also found the rooms to look very similar which can make navigation a little difficult. I also don't think the coins mechanic was super necesary.
Great game though :D Congrats
