Frankenstein: The Monster Returns

In this horror-themed side-scroller, you control a self-named hero tasked with defeating the titular fiend and rescuing Emily, the village elder’s daughter. You begin equipped with your fists and a jump kick, but will permanently acquire swords at the end of the first and third levels. Certain defeated monsters also drop weapons, like clubs and slings, that can be picked up to increase your attack’s strength/range.
