1. Try not to think of any direction as "up". It takes a while to get used to this, but once you get over the initial vertigo it becomes easier to navigate the hallway effectively.

2. Don't try to get every box. Go for boxes that are already on your route, or boxes that are not near walls or hazards if possible. You lose a box for every few seconds you don't collect one, but staying alive will advance you faster than trying to play perfectly.

3. When you flip upside down, you fall through the air before landing. You can take advantage of this by double tapping flip to float momentarily, which can help to navigate certain obstacles.

4. Remember that when you flip, right and left will be reversed from what you saw before. if you need to flip and then go left to avoid a wall, hold right when you flip.

5.The box moves more slowly from side to side than it does when you flip, so sometimes sideways motion won't be fast enough to save you. Get used to flipping the camera frequently.

6. Don't be discouraged by the difficulty. Once you get lower levels beaten consistently, you can start practicing the higher levels.
