Good concept but no challenge
All I’ve had to do is upgrade damage and some fire rate and I’ve been steamrolling over every wave since wave 10 without care. Grenades are broken(overpowered), enemies to not increase in health as waves increase. It’s just too easy and already far too early in the game. Get fire rate up to 4 and simply focus on damage and you’ll be set for life. Good concept, no challenge though.
