If you've not yet experienced the joys of launching yourself around tethered to your own filth (in a game, anyway), please do check out the latest game being given away free on the Epic Games Store: Yoku's Island Express. It's a charming metroidvania-ish pinball platformer where you take control of a wee dung beetle postman who propels himself around the pretty island by batting his ball of filth with flippers conveniently stuck around. Delightful.
