Absolutely beautiful. Such a polished, well-defined concept. So fun, and the right level of difficulty (even though there's one door I still can't figure out... <3)
The groovy beat is perfect, and graphics are comforting while the gameplay is very engaging. I love this concept; I wish there were lots more doors; I feel like it's making me smarter 馃榿馃榿
Edit: I think Gone Fishing and Escape are the only two that can solve themselves.
