I liked the hand drawn gun and the revolving arena, unfortunately audio didn't work for me, I stopped being able to shoot after a while and didn't know how to reload, and was unable to move forward or backwards, just side to side. Enemies eventually reached me, but I didn't take damage, so I had to force quit.
I think like previous comments this game could've used more UI or a tutorial, and personally I would've loved seeing more of that 2d art like the gun in-game.
