Closure jumps from PlayStation Network to PC and Mac next week, Eyebrow Interactive confirmed today. On September 7, the 2012 Indie Game Challenge winner releases on Steam for $10, coming in at $5 less than when it released on PSN back in March. The light-orientated puzzle-platformer also brings extras to its Steam version, including a developer commentary mode unlocked after beating the game.

Programmer Tyler Gliael and artist Jon Schubbe are showing the game off at PAX Prime this weekend, but in the meantime you can check out Richard's review for a glowing reference.
