[Classic] Sonic the Hedgehog Genesis, great game or GREATEST game?

I didn't think the BGM was bad, but the SFX is a total loss. And the framerate is visibly choppy. No excuse for this.

Thank god I didn't buy this one. The only GBA Sonic Game that was good really was Sonic Advance 2.

Jam it back in, in the dark.

Other "glorious additions":

*speed shoes don't let you go any faster
*loop jumping doesn't work at all
*jumping no longer reduces your speed at all
*jumping on upward slopes to jump higher barely works
*jumping out of a roll leaves you in full control of movement during the jump
*you don't stop moving when you land after taking damage
*damage always knocks in the direction you're not facing
*you can't bounce high off of item monitors or enemies
*you can't push blocks during a jump
*bosses don't reverse your speed when you hit them, instead it matters where you hit them
*bosses push you away when you hit them even if they're still invincible
*you can jump through slopes if you hit them while still moving upward
*zipping doesn't work anymore
*if you press in the direction you're already moving while running backwards, you instantly stop
*in general, when moving at a high speed, the only effective way to slow down is to press forward (in the wrong direction)
*you can jump into and out of lava or fire without taking damage
*if you beat Labyrinth 3 too fast, the game freezes

There's nowhere I can't reach.
