The game is overall pretty fun with the upgrade choices that you have, but one major complaint I have is that the movement is pretty difficult, especially when you have the spike. in order to turn around you have to press both d and s which if you're getting attacked, it can slow you down enough to get caught. Another thing is that the heal option doesnt actually work, and after about three levels the monsters start spawning in so frequently and are so large that I found it impossible to kill them without getting hit myself. I wasn't able to progress past three levels. I love the art style, sound effects, and particles. Great job!
