Proof that Madness Combat was copied by Thing-Thing:
Watch a Madness Combat episode, then watch the beginning scene. They are intensely similar, but these episodes will match better:
#5
#6
#7
I beat this very quickly because of three things:
1: PATIENCE. The key is on the midsection of the platforms SOMEWHERE. JUst keep looking.
2: PRE-PLAY. If you'd played before, or, even better, beat this before the badge, it's a hell of a lot easier.
3: PRACTICE. Learn when to run and when to kill.
The easiest tactic for defeating a Sharp: Make a sharp, close U-turn next to it, and it may retract its spikes. TAKE THIS OPPORTUINITY. If you have a reward key, look for an offensive weapon, and use it to attack the Sharp when its guard is down.
