The aim is to collect all the bananas and land safely on the platform before your fuel runs out.
Fly in your space craft collect bananas and other fruits and land on the platform in time to complete the 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.
