The idea is really solid. Music is good, visuals are great. The reason of spinning and the use of it is really creative.
You did not state in the description that r is reload. I mean it is obvious, but i didn't try for so long, because it could've been from drops too. Maybe an indicator to press R when you first empty your gun would be helpful. Then I realized that i can reload the gun. But i couldn't really use it, as the spinning was too fast for it. Don't really know how to fix this issue tho, maybe have aimbot or something.
But apart from that it was a really well made game!
