Great job! I really enjoyed the combination of turn-based combat with block puzzles. There was a surprising amount of thought I had to put into each turn as the levels got more and more compact, and I think that overall the presentation is great too.
The main thing I would have asked for is a fullscreen mode, as I felt I had to squint sometimes while I was playing.
Other than that, though, I think you did a really good job designing this one. Awesome work!
