Neat little game, though my hand definitely felt it by the time I finished xD Everything was pretty intuitive except for what the middle upgrade was. My best guess is that it's crit damage or crit chance? There was a level up perk for crit too, though it wasn't clear if it was damage or rate (or both) either. An addition to the stat block would be helpful in clearing things up there. Either way, keep up the good work!
