Really good shooter, but it is a hard to tell that you need to press r to restart, and in fullscreen mode the UI didn't scale quite right. Sometimes the enemies would go off the screen whenever they were packed closely. One suggestion - a lot of time when the enemies spawn on top of you, there is nothing you can do, so maybe give a warning signal where an enemy is about to spawn.

The screen is all black for me, is that happening to anyone else?

Game feel is really good, its a  well working top down shooter. I really liked the music / sound in this one. :)

The controls are responsive and intuitive and I really liked the small effects, like the screen shake and the particles. Its a cute, fun game!

Nice shooter. Would have been nice to have an instant restart button
