This remarkable logic and speed game based on a brilliant concept carries you in a paradoxical universe: a scene in black and white, entry, exit and a character that should join the two. Simple, a priori, but press on the "Shift" button and the world falls over. The black becomes white and vice versa. This is yours to find there again in this world where the floor becomes the ceiling and the ceiling becomes floor.
Heat up your neurons to solve the various levels that are getting much more serious!
The arrow keys allow you to move and the Space bar to jump. Pressing Shift reverses the scene. The key P to pause and enter the menu.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
