I Apologize for taking it WAY to easy here. I won't do it again i promise. For this level the only real chanllege is using the bike to get the Heart piece.

Remember you can boost with the Dash button. Also You must shoot down the barriers to go over them. You must be fast and time your jumps, it's pretty hard. Finally to get the piece you can crash into the spikes and die. Do a quick U-TURN as shown to get the piece.

The upgrade is simple to get just use Spin Wheel on the noticeable barriers. For the Scorpions take them out with Spin Wheel. Strike Chain on the Little bug shooters early on in the stage.
I get hit on the last enemy before the boss. Just use Spin wheel on him from far away and you should be fine. I got very unlucky.

For Overdrive Ostrich. With some practice he could be the easiest boss. Basic X-Buster shots take 2-3 health even 4 maybe with one shot. His attacks are easy to dodge but this is without a PERFECT no damage. Once again I apologize. The rest of the videos will be PERF :)
