Madou Monogatari A: Doki Doki Vacation

Four-year old Arle Nadja goes into a forest near her grandmother's house but becomes lost getting distracted by Carbuncle. Along the way, she is granted powers from magic forest fairies, who teach her multiple spells. In the original version, Owlbear is the final boss who you run into constantly. This was the only game to be remade and ported onto the Sega Gamegear (known as Madou Monogatari: A Doki Doki Vacation), but massive changes were made such as different enemies. There was also Satan being the main villain and final boss, and an entirely different intro where Skeleton-T, Sasori Man, and Suketoudara make a cameo.
