Cool game! I've played some typing games where words fall down and you have to "kill" them by typing them out. You've managed to add combat style actions and stats system to make it more interesting. Found it pretty hard. Got to wave 7 and a score of 4.5k. Really like the "Bash" kind of combat mechanics and also the upgrade selection which has diverse choices like enemy changes, score bonuses, spells and defenses. Good job overall!
