Drag the dot through the maze and from level to level.
Even so, your PSP is not a brick. You can easily turn it into one, however, by failing to treat it with care. It's a little too big to be a paperweight, but it would make a fantastic doorstop, as you'd expect at its high price. If you want a doorstop, go to the hardware store and buy one. If you want your PSP to work as a PSP, treat it with respect.
