The exe didn't install for me. It gave an error about licensing. But the zipped game played without issue. The screen was a tad big and off the edges so I couldn't really see the controls well but he game played very intuitively. The movements are nice and snappy feeling. I like the gridded movement. Having multiple levels to flesh out the mechanics was nice. Sound effects are good. I will say that the music gets tedious after a few levels. The puzzles, of course, are great. Not too difficult, not too easy, and the challenge scales as you progress. Nice job.
