Control with the mouse. It will go into the direction your mouse is, and as farer away it is, as faster it will move. If you click somewhere above it, it will shoot a ball, which can kill monsters. Jump on the platforms to jump. Try not to fall down or get hit by monsters. If you jump on a monster, it will die and you can use it as a platform. (You jump higher on monsters than on platforms) Sometimes there are platforms with trampolines or springs. As you probably already suggested, you jump higher on those. You can also find black holes. They'll kill you. If you higher the "multijump" button in the main menu, it will higher your jumps. (how high you jump * multijump). The default is 0.8.
If you put the "multijump" higher than 0.8, your highscore won't be counted. The sound and the textures are copied, but the code is all done myself. note: if you get earcancer from the sound, it isn't my fault! SPOILER: there is something hidden in the mainscreen :3
