I created this game using an awesome game creator called sploder.com.
How to play: Use the arrows to move (You can use the down arrow to move underwater). You can jump on top of most of the monsters heads, but most have multiple lives. You can collect coins, which you use at the end of each level to upgrade movement, health, and strength. You may sometimes see blocks stacked on top of each other. This means that you have to kill a certain monster in order to get through. There are also other things like mushrooms, vines, and other stuff that you can find out in the game. Have fun!
