Warp to Level 3
In level 1, look for sewer lid out in the water. Open the lid and you'll be warped to level 3.
Warp to level 5
When you reach level 3, move left and down along the narrow passagewith the tricky jump to reach an open area with two speakers. You must reach the highest manhole cover. Jump to the right coverand get a speed-up. Next jump on the platform to the left of the dispensers. From here jump to the right of the lefthand speaker and open a cover hiding a clock. Now jump to the platform on the far right of the speakers, now jump to the final cover and open it to warp.
Warp to Level 8
To warp to level 8, finish the first level in 4 seconds. A rocket ship at the end of the level will fly you to level 8.
Points
On level four, go to the scales and move right, a yellow anvil should appear, as soon as it does jump back on the scales for 5000 points. You can keep repeating this.
