Funny little trick I found:

Not sure how useful it is -- setting it up relies on the random position of the cube, but it's pretty easy to do. Just make sure you're above the cube, and then hold dash into it. Maybe has some application somewhere.

Mega useful. As a matter of fact that simplifies the Level 5 boost I found yesterday, since the position of the cube can be manipulated by the player based on proximity, it's just a case of luring it over and landing the boost.

Can most likely be used on other levels as well. Can't think of anything that'll be greatly improved off the top of my head, but I've no doubt there's at least one other one we can find.
