The player controls a cube, which moves upwards on a vertical block. From top to bottom on the block will go obstacles - triangles. The player must not get caught on them. To do this, you need to change the direction of the cube (on which side it moves). The cube can be controlled by pressing on the screen, then he jumps to the other side of the vertical block. If the cube falls on the triangle - the game ends.
The task of the player to stay as long as possible.
For each triangle that the player manages to bypass - you can get one point. The more obstacles will pass by - the more points you get.
There are two levels in the game - easy and difficult. Mode determines the speed at which the obstacles will appear. On simple obstacles will appear slower, on heavy - quickly. The mode will have to be selected before the game starts
