Really cool game!
Always love some hack and slash, and I love the level up system
Only made it to waves 6 or 7 or so, encountered some odd movement bug but overall was fun.
I couldn't figure out how the level up system worked, was only able to level up the stats twice.

Thanks for playing! :)
Essentially you get XP when you kill an enemy; around wave 6-7 your character should probably be about level 6-7 (although the number of enemies spawned during a batch of a wave and the XP reward for a killing an enemy are both randomized slightly). You get one upgrade point when leveling up. The "Upgrades" button only shows up at the end of a wave if you have upgrade points to spend.
