The track, forces, pacing and roll points are spot-on. It's the perfect amount of roughness that every boomerang has, which doesn't make it that enjoyable, but it makes it more realistic. I think the supports look a little too thin compared to real boomerangs, although they are the right shape and in the right positions. I realize that it's a generic boomerang model, so I'll try to not have scenery accuracy and attention to detail affect the score. Although it will move the degree of difficulty down a lot. So this isn't anything mind-blowing, but it's a solid re-creation.
Edit: The difficulty was raised, since there actually aren't as many boomerang re-creations as I thought, so the track was really hard to make from scratch.
