So this is basically Sonic 1 for Genesis, but with two key fixes that should've been there from the start. First, they patched that annoying spike bug where you'd randomly die when touching them at certain angles—no more unfair deaths. And second, they added the spindash move from Sonic 2, which makes the early zones way less sluggish when you're replaying them.

It's still the same classic Sonic you remember—Green Hill Zone looks just as vibrant, the physics feel right, and that soundtrack hasn't aged a day. But now you can actually enjoy it without some of the original version's jank. If you're gonna replay Sonic 1, this is definitely the way to do it.
