In this game (in the full game with the monster) you use all the buttons to knock out monsters using Rage Points. Rage Points can be used to summon Minions or a Killing Crushing ROCK of doom that sends the monster back to the beginning, and if you hit retareat or te monster knocks u out and gets to the heart jewel up on top of your tower, you lose.
