Sonic the Hedgehog Genesis is an infamously bad port of the game; the game suffers from huge slowdown and frame rate issues, Sonic feels like he's running through honey, but then will suddenly speed up unpredictably. The physics and momentum and messed up, Sonic's jumps not feeling right and the momentum is so bad that Sonic will continue to move forward long after you've stop pressing forward. The music sounds terrible and this cannot even be blamed on the GBA sound chip as Sonic Advance has tracks from Sonic 1 on it and they sounded great. Lastly, there are numerous glitches and bugs present throughout the game that do not exist in the original

I implore that you replay or look at footage of this game because all of these issues are clear to see.
