So, Sonic Winter Adventures—it’s this weird little beta ROM that popped up years ago, supposedly from an unreleased Sega Genesis holiday game. You’ve got Sonic running through snowy zones, smashing ice blocks, and dodging snowball-throwing badniks. The physics feel a little janky (it is a beta), but there’s something charming about the half-finished sprites and glitchy snow effects.

First level throws you into a frosty Green Hill knockoff with slippery slopes and these weird penguin enemies that slide at you. No rings in sight at first—just a bunch of frozen loops and half-baked platforms. Feels like someone’s unfinished winter mod, but in a fun, "what even is this?" way. Music’s a muffled remix of the usual Sonic tunes, like it’s playing through a snowstorm.

Honestly, it’s more of a curiosity than a full game, but if you’re into obscure Sonic stuff, it’s a neat five-minute distraction. Just don’t expect polished levels or a proper ending.
