It was a good effort for translating the 16 Bit game onto a smaller cartridge epically under the time constraints however their is difficulty spikes that make the game less fun.
Hard but in the worst way possible. Awful gimmicks like the hang glider and a million of tube puzzles as well as bad level design make this game unplayable.
I wish that this game would get an actual port so that it can be easier to play since MAME is kind of a hard emulator to use. (unless your Billy Mitchell then you use MAME to cheat all the time.)
The physics and mechanics of Sonic Spinball aren't that great and besides a rocking soundtrack and neat cameos the game doesn't offer much in terms of fun.
