@najimi@hellsite.site oh it heckin' is. There's a direct sequel on the megadrive, called Sparkster: Rocket Knight Adventures 2, but there's also a game called Sparkster on the SNES.
now, Sparkster on the SNES is utterly unrelated (aside from the main character and his rival, and the basic gameplay), but despite having absolutely NO continuuity or even link to the original, it's DEFINITELY worth a play. the SNES version is pretty great tbqh.
