they took sonic spinball and made it somehow janker and really really easy by showering lives through bonus levels. Plus they totally changed toxic caves making me think that the level layouts are completely different, then pranked me by having the other 3 levels basically downscaled versions of the 16 bit counterpart, which kinda ruins the whole curiosity of what else they could have changed. Other than that, it's sonic spinball. The game gear version probably has bad screen crunch so not sure if you should give that version a shot. either way play the 16-bit version instead.
