Archer Maclean's Mercury Cheats

1. Cheat: Sometimes you can jump walls or skip past gates by running the mercury up a ramp to be on top of the wall. Move the mercury down the wall and drop it where you want. It takes precision, but it can be done.
2. Hint: When the level lets you win with very little mercury left in your meter, usually there is a trick to win the level quickly. For example, when you first reach the snow level with the conveyer belts that shoot you up, you can jump off from the very beginning to the belts, skipping most of the level completely.
3. Unlock: Get the high score on each level in a stage to unlock a bonus level
