From the past, not a blast
Not to be confused with Sonic 3D Blast, Sonic Blast only really shares a fondness for rendered sprites with its 16-bit namesake, sticking to more mainline Sonic staples like running, spinning and grabbing Chaos Emeralds. The rendered sprites weren't particularly impressive back in 1996 and they don't stand up too well...
About The Game
Sonic Blast was released for Game Gear in conjunction with Sonic 3D Blast (aka Sonic 3D: Flickies' Island) for Mega Drive and Saturn.
It boasts similarly rendered character sprites and colorful backgrounds. The game was yet another addition to the series, plus Sega had hoped it would be a boost to the dying Game Gear's title selection at the time.
