I was initially a bit confused about how to shoot. I was just clicking when I wanted to shoot, which sometimes didn't go through, so I thought I had to restore my shot somehow. Eventually I figured out how to, but I wonder why not just have the player constantly shooting if there's no reason not to anyways?
Enemy spawning was a bit wonky sometimes, I was only able to get a score of 9600 because of it. Visual effects are very juicy and the music is interesting. Overall a solid game!
