Play the game for at least an hour or two before using the CD as a real-life Frisbee. It does get better with time the physics are actually quite good and you will reach the point where your control has matured enough that you can pull off aneuvers
you once thought impossible.
Your choice of throwing styles backhand, forehand, added elevation, and so forth is perhaps even more essential than your choice of discs. A backhand throw will curve to the left, a right-handed throw will curve to the right, and each can be used to bend that disc around even the most formidable obstacle.
The game's main viewing widow does a poor job of conveying depth and distances. Refer to the top-down display at all times to read the topography and location of obstacles effectively.
