You only get half the points each time for repeating tricks. Dont fall off the tramp. Use LEFT and RIGHT ARROW KEYS to control the rotation, and use the UP and DOWN KEYS or YOUR MOUSE to select a move (shown on the right).
You have 99 seconds to bust as many trampoline tricks as you can.
Tomb Raider: Legend on the GBA delivers a solid platforming experience that actually manages to mix in a healthy dose of the gunplay and puzzles that the console versions contained.
