Wow, excellent work. Visually, this is spectacular. It's one thing to make nice models and graphics, but you created an adorable character and themed levels. I love the puzzle-on-top-of-another-puzzle design. Reminds me of the last dungeon in Skyward Sword. I'll admit I gave up on the last one when I died and lost my progress :( I'd love to see this expanded, maybe with a couple of easier levels to get a hang of the mechanics. And maybe don't re-hide the rooms when you die! That felt too punishing.
Some minor criticism - I kept getting hit by traps before I saw them. Mostly from walking/ falling through a door and dropping into them. Also, I liked the movement, but had some trouble getting through the doors. Maybe enlarge them and/or remove the ledge around them?
