I like the art, story, music, and cutscenes, and the gameplay concept. However, the "powerup" cards you get make it feel less like a pure puzzle game. The idea of making puzzles easier by giving assistance to the player is good, but I feel that the puzzles should also be possible without using any cards. In addition, I don't see how the theme is implemented. Other than these, the mechanics, tutorials, and level select are implemented quite well. Great work!
