nice visually but very difficult...i managed 1 kill, the placement of the enemy spears was questionable. I think the spinning mechanic is funny but the enemy reach is way too much so you can't enjoy the spinning properly.
I gave it another go and found the upgrades, i thought the cups and weapon racks were just props not upgrades. Some kind of tutorial or maybe particle effect or glow around the upgrades would have helped make them more obvious.
