Alright so you can get trapped here (The room where you dodge spikes with the anti-gravity effect). If you miss the checkpoint here, get the team switch and then die to the spikes (Which you have to if you get the blue coin) you get respawned back up at the top with the anti-gravity and you can make the jump over and touch another team switch, you get trapped, because you miss the coin in the room with the fly effect.

I'd post pictures but it doesn't allow me to post links or images. I'll PM them if I can.

You can also exploit the room under the spike room (The one with several boosts/dots for the cyan switch) by holding space and jumping from the bottom part immediately to the cyan switches.
