Great game! Use the "z" key to modify your power (It comes in handy for progressing in the game!).

The portal back to the beginning of the game doesn't work:/ ...good gameplay though. Interesting weapon and character upgrades.

I can't figure out how to damage the second boss robot... jumping on his side levers brings his head out of hiding, but attacking only slows him down..

Upgrades are too easy to achieve, wish there was a greater range

A good recharge on the booster bar is well worth the time, and pushing a green block down in order to bump an adjacent block up helps!

Hmmm, can't get past New York, and can't upgrade the racer anymore..
