Eyebrow Interactive's light-manipulating puzzle game Closure is $4.99 on Steam for PC and Mac and the PlayStation Network today, the developer announced on the PlayStation Blog.
The PSN discount begins today and runs through the week, while Steam's discount ends on Thursday, Nov. 1.
Closure has players move through levels in total darkness without falling into an abyss, using light bulbs and portable spheres of light to illuminate platforms and walls. The game was originally released as a Flash game on social media and entertainment website Newgrounds, and won the Innovation Award at IndieCade 2010 as well as the Excellence in Audio award at the Independent Games Festival the same year.
In March this year Closure was released through PSN for PlayStation 3, then to Steam in September. Last week the game won the Grand Prize for the GameStop-sponsored Indie Game Challenge.
