Fun game. I like the retro aesthetic, the music variety, and the idea of making pickups as persistent rigidbodies.
I stopped at wave 11 because I got a bit bored of the lack of weapons and enemies variety, but still a nice and solid wave shooter.
Thanks for playing! Yeah, I think most stop around that point. I'll try to add some kind of mini-boss at 10 in a next update and rework the difficulty curve.
