Very cool idea, I like the spin of the weapon not flying around you but you having to control it with momentum.
Sadly it is a little buggy here and there. In some rounds my whole upgrade UI just disapeared and I had to play without upgrades and the Cane also got stuck a lot at places where I´m not sure that it was suppose to be stuck there. I would also agree to the person beneath me about from where to shoot.
But I like where this is going and I would try to fix these bugs and polish the game to have a cool project to show to friends and family. :3
