Neat puzzler! Got pretty tricky at times, but I had fun solving the puzzles. The difficulty curve was a bit all over the place however, where you finish a really easy stage, then suddenly a really hard stage, and then it's back to easy, and so on. I guess it did keep it fresh somewhat, but I'd prefer a more gradual increase in difficulty (though I know that can be tricky to determine). For example, as early as level 4 there was a really tough level to solve considering it was still in the kinda tutorial period! Controls were a bit frustrating too: because of the diagonal view, sometimes it tricky to tell, for example, where pressing a direction will actually send you to. Obviously not an issue if you use the touch controls in the corner which are angled appropriately, but for keyboard arrows, it gets confusing. Anyway, at the end of the day, I had fun with the puzzles and it was put together very nicely in all aspects, despite some difficulty bumps.
