This is such a cool concept!! I really liked the spin attack mechanic, it was really cool, plus yay for gambling. Unfortunately I guess I increased my damage way too much, because after the second time at the upgrades screen I basically couldn't move my character at all despite increasing movement speed and strength a ton, so I died pretty instantly on wave 11, but still a really neat game! The music and sounds were great, and the visuals were quite polished. Great work!
