This is Blacked 2! Use arrow keys or awd to move. You have to get to the other side. There is no wall jumping to make it harder. ALL LEVELS ARE POSSIBLE!!! The music changes in every biome. There are 30 levels. Better playing fullscreen! If the music notes are too distracting, then click space. If you want them back, click space.
