A note about my judging: My rating scale starts at a baseline 3/5, anything good done raises a score, things that are less good can lower a score. Genre is rated generously. As a game-developer I know that when giving feedback, while I can give suggestions, it's up to you as the developer to determine what accords with your vision.

4/5 Enjoyment: Generally enjoyed myself with this one. I wouldn't write home just about this game, but it would merit a mention if I were writing a letter about MVM.

3/5 Execution: I would give more control options to the player; there's little reason for arrow keys not to be supported here, for example. The puzzle assignments were easy to understand. Points for telling the player where a block will drop.

4/5 Sensory: Music is nice and listenable. Graphics are simple but very communicative and cute! Sounds are neat.

3/5 Metroidvania: You do a small amount of backtracking to use a power twice (one on the same screen), but fundamentally the vibe is still a bit more puzzle-platformer than gated exploration. A larger overall world would probably get closer to what this game was going to be--and if it were it would probably be much more clearly on-genre.

Overall: A pretty neat game. Shame it's so short.

This game is very short, but shows promise. This game would be great in browser. Nice music!
