This has a simple but really fun gameplay loop from level to level. I was able to beat every level, and the difficulty ramped up pretty organically for the most part: some levels had me pretty confused, but with the right strategy, I was able to prevail. Really efficient use of assets, too: all the enemies look and behave similarly, but they're distinct enough that I can gauge their behavior in less than a second, which definitely becomes important in the later levels, and the way the level design takes advantage of their behavior really works to the game's advantage. And I didn't even touch on the amazing sprite art! Overall, great stuff, and a satisfying experience from beginning to end.
