Instructions are in the game.
I added a new feature to the game, now you can shoot enemies by pressing and holding the spacebar to kill them. Not all of them, that is, you can't shoot the goo enemies because you can already stomp on them. And you can't shoot Lava Balls.
Notice: Don't go near the poof you see after you get rid of an enemy, it can still hurt you.
Love, fave, and follow!
