This is a really challenging game. For me, it was less of a tower defense game and more of a puzzle game, which isn't a bad thing. The crossover between the 2 genre is pretty innovative since it combines the elements of precise tower placement and critical thinking. It felt satisfying to watch the game play out once I figured out where to place the towers. I also like how there is a pattern for the enemies spawning. It makes the game feel easier, although it's not really that easy. Sfx and music will really make the game "pop" more and feel more fun, especially since puzzle games take real long for some people(like me). Nicely done!
