Vertigo

WARNING! Playing this game for extended periods of time will alter your visual sense of perception. Be careful which environment you play in and maybe have a vomit bag on stand-by. Vertigo is a simple ball popping game. The bar on the right of the screen changes color and you have to fill it by popping the same colored balls. Hit the wrong ball and the level goes down. When you fill the meter the game will speed up and change colors. Each time you level up the balls will move faster and faster, requiring more concentration. To get the visual effect in the real world make sure you don't take your eyes off the screen. At some point it will be almost impossible to play. This is when you should look away from the screen and you will see the real world warp and move with your own eyes. If you find it disturbing then it shouldn't be used again. However it is a fun trick to play on friends who are looking for something visually spectacular.
