Very nice core mechanics with a lot of potential. The turret rotations make me want to set them on fire, when they do almost a full circle to chase the next target instead of just turning the other way. Will be a very fun game once a bit more content is added.
The gravity mechanic is a really cool idea, especially when the balls want to orbit instead of hit anything. The linear progression lets everything down, unfortunately. I've not hit level 400 yet, even after hitting 300 on my first run and leaving it on overnight with a whole lot of upgrades.
well, it's like in the old movies, if the rotation speed is at the certain ratio with the framerate
