Mega Man: The Hedgehog Trap (Extreme Mode)

Mega Man: The Hedgehog Trap (Extreme Mode) is a harder version of the fan-made ROM hack The Hedgehog Trap for the Mega Man series on the NES (Dendy).

Extreme Mode is a separate version of the hack with increased difficulty compared with Normal Mode: enemies are placed more densely, bosses are more aggressive and there is even less forgiveness for mistakes. The name refers to Sonic the Hedgehog, and the hack includes elements inspired by his universe.

It is a tough challenge for experienced fans.
