So at the start its fairly simple, its here i also do most of my restarts, also you do not need to do tricks in the first few levels because bonus time is not needed. You can save a lil time by not getting great score on these levels.

you can "clip" on top of some high objects by jumping from behind them.

The Tech Decks just under the half pipes you do not need to ollie (unless they are not very tall).

Ollie over all obstacles, par some objects like the cup and the ball(easy to learn where these are after 1-2 playthroughs).

I like to aim for the actual deck not its shadow.

If you are at the edge of the map it can be worth changing angle to collect the deck as you can keep some momentum for the next.

play with control styles, there is 2 to chose from one might click better with you.

I play with a Gameboy player for GameCube, this allows me to use analogue stick rather than the GB d-pad.

Don't be scared to restart, its a short run after all, better to restart a bad run than waste time finishing.

leave music on for full frustration.
