This game is super super fun, however I have 2 things that take half a star away from my rating. One would be the controls. I constantly run into the spikes trying to kill them, and maybe that's because I'm not a great gamer, but I thing it would be a little bit easier to have a mouse +wasd or mouse + arrow combination for controls. One other small thing is that it takes FOREVER to get a lot of XP so I can purchase upgrades. Maybe the monsters could give a liiitttle more XP per kill.
Anyway, I do enjoy this game a lot :D Thanks for your time
