If you spot a question mark near the top left of the screen during the level, it means there's a Secret File hidden somewhere. Start digging! Try digging away all of the dirt to find it, and then restart the level with the knowledge of where it's at.

Pay close attention to which Crazy-inators are doing what in the level. In other words, don't accidentally lead all of your water to the confetti one.

Restarting the level is as easy as a tap of the button on the top right of the screen. Don't be afraid to take advantage of that.

Don't let the gnomes come in contact with black sludge or lava, they'll immediately disappear.

If you're being subjected to a cutscene you've already viewed, a double tap on the screen will skip it.

Some levels start with water immediately flowing like crazy. To give yourself some extra time to think, dig a pit for the water to rest in.
