Proteus is a warm, soothing bubble bath for the soul. The lo-fi first-person explorer lets players loose on an island that’s one part rainbow dreamscape and another chirpy chiptune music maze. Basically, it’s what I imagine nature lovers believe the outdoors to be, even though every real-life forest, hill, and tree is actually made entirely out of spiders. And yet, for all of Proteus’ high-minded inventiveness, it certainly didn’t start out that way. Creator Ed Key had to learn some very important lessons about, er, not being Skyrim before his first independently developed game traded bullets for butterflies, and – despite Proteus pulling in a fair deal of money – he’s trying very hard to keep them in mind for his next game.
