It dawned on me that I haven’t really played much with romhacks in awhile, so I browsed the Steam Workshop and found Sonic XL: The Mod No One Ever Asked For (I may be paraphrasing), and much to the description it remains true. In this version of the game the traditional rings have been replaced with tasty onion rings, and the more you collect the fatter you get. Of course you can burn off the fat by running and finding a random powerup to make you magically thin again, but in certain points that’s easier said than done. If you eat too much you’ll be too fat to do a spindash, or even stop moving entirely with a heart attack taking place shortly afterwards.
There are different custom sprites for each stage of fat ranging to pleasantly plump to DAMN! Nothing else about the game has changed, so it’s not the largest edited Sonic rom I’ve played with, unless of course you mean just the Hedgehog. :v:
