Awesome game, the art and the background are awesome and the powers ups felt really nice :D, at first I though I had a bat and was trying to hit the enemies with it haha, I would suggest giving some time after the wave ends and the power window appears because some times I was shooting and the window suddenly appeared and I clicked on a power up without even reading them, but overall very cool :D
Also hope you can rate our game https://itch.io/jam/brackeys-6/rate/1177206
