Ultimate Prank Game

Lost Ultimate Prank Game is a screamer game/video uploaded to YouTube by TingSing on June 8, 2008. Though it is a game, there is no download link and, according to the description, there won't be.

It starts off with the user (presumably TingSing) opening up the application file for the game stored on the computer. After loading, the game immediately begins, revealing it to be a maze game with red areas, a multicolored orb as the control, and a glowing rock as the end. The first two levels operate like a normal game, but just before one can complete the third level ends, a picture of an hooded boy with fangs, glowing eyes, and scars pops up along with the same scream used from Sonic.exe.
