Excellent! The game is clever, all the controls are intuitive, and the minimalist art style both serves the game and looks good while doing so! The core idea is clever, but the real star of the show is the level design. At first I wasn't convinced by a puzzle game not showing me the whole level, but the levels were laid out so neatly that I got a real sense of discovery rather than the confusion that I was expecting. And great job on the last level as well, great way to top off such a clever game.
