A fun mix of tower defense and puzzle, really interesting take on the theme. It was fun to trial and error what worked and what didn't. My only very small critique was that most levels I did not feel the need to stack turrets on top of each other but maybe that was just the solutions I was coming up with and not intended solutions. Regardless still a lot of fun and well polished. The fact that bullets all fire at the same rate made for some cool puzzles.
