The Legend of Dark Witch is a 2014 game first released on 3DS and later ported to PS Vita and PC, with a PC Renovation and Switch remake coming later. It features a Mega Man-like gameplay with a Gradius-style powerup system. The first in the series, it features Zizou Olympia, who sets off to investigate the theft of the Syega Crystals.
Darkman425 brings Riva to reason on Normal difficulty as Zizou in record time, both of which being the hardest difficulty and character available from a clean save file. The actual hardest difficulty, Lunatic, is only available after clearing the game once on any difficulty.
