Okay, so this is one of those wild Sonic ROM hacks where someone mashed up Sonic 3 with My Little Pony—specifically Rainbow Dash. You're basically playing classic Sonic levels, but now you're a blue pegasus pony instead of a hedgehog. The physics feel a little off at first (ponies don't spin dash, apparently), but once you get used to the floatier jumps, it's weirdly fun seeing Rainbow Dash blast through Green Hill Zone.

The sprite work is actually pretty decent—Rainbow's animations are smooth, and they even gave her a little rainbow trail when you hit top speed. Some of the level layouts are tweaked to work better with her flight mechanics, though you'll still faceplant into spikes if you're not careful. It's janky in that charming way only old-school ROM hacks can be.

Definitely more of a novelty than a serious platformer, but worth a laugh if you're into bizarre crossover mods.
