Gravity Switch

Maneuver your way through space by switching gravity and avoiding the red walls. Reset a level with R if it's impossible or simply too difficult. Get to the purple square to move onto the next level. 

While in the game, press ESC to go back to the title screen to switch the difficulty. Don't worry, your progress will save.

The first number is the level you're on, the second level is how many times you've died on this level, and the third number is how many times you've died in total.

Pressing the skull makes all the walls except the right one deadly, and touching any one of them kills you. This makes for an extremely difficult experience.
