asdw and arrow keys. You have three lives the blue circle that in a random spot will give you another. Try to avoid red, because one touch on red kills you. There is a checkpoint for every two levels. The purple rectangle will poison you if you touch it. There is a antidote though, it is the yellow circle. In easy you get two extra lives. In normal you get three lives. In hard you get three lives but the blue circle doesn't show up.
