Sounds like collision's wrong and people could use this for slides XD. I can already hear the Mario Slide theme XD.
Collision isn't wrong, the only issue is that sometimes you(for whatever reason) fall through the floor when you spawn. This can be resolved by placing a spawn brick(which you wont fall through).
The only other issue is that you sometimes clip against random sides of bricks that you shouldn't, its rare and there's nothing you or I can do about it.
At any rate, its perfect for slides as you can make them using smaller ramps and still have the player slide on them.
Also, if someone were to make a good sliding arena(ramps to gain speed, obstacles, etc, would be fun), I would put the save file on the first post.
