You’re incredible! Trophy

Warning! The last boss of the game may glitch on you if you kill him while the flying saws are away from his body, making the boss get stuck in his dying animation but not actually dying. To avoid this happing to you, wait until the saws are circling the boss before you kill him.

There are 10 levels in each chapter that you need to clear, each ending in a boss fight. The bosses have red weak spots that you need to hit, remember to change worlds to reveal hidden spots. The second boss, unlike the other, will not regain health if you die while fighting him.
