Very cool game, I love the aesthetic, all of the graphics and animations are crisp and nice to look at, the enemy follow mechanics are smooth, and the way your shot origin points change forces you to change up your playstyle based on your shape, which is a cool way to keep a single level game engaging. The only criticisms I had were that wait time between enemy spawns sometimes felt a bit lengthy, and the fact that your shot could move through walls made it so once you were at 5+ sides, you almost stopped needing to aim and can just spam shots and kill everything even if you couldn't see them. In later waves I killed more enemies off screen than on, so in spite of enemy types having more attacks, they almost felt easier because of this, so either making your shots not pass through walls or not letting your shots travel more than a set distance from you would help maintain the difficulty.
