I don't like the controls; I get too bouncy. In particular, your bouncing doesn't preserve momentum; when I go fast sideways and slightly down, then bounce at the bottom, I bounce up fast, instead of with the same slight speed I had down before. Also, require less mouse clicks in a keyboard oriented game.
@Walr688: Move to one of the most left corners of the high land. Then build a turret on the highest ground as fast as you can. Make sure your turret (and succesive mortar) have enough power to keep the creeper at bay on the high land.
You can play full version on my website or mobile, it has no limitations.
