Since Steam opened up Greenlight it has given all indie developers a shot at getting their game on the service, regardless of how good or bad it may be. Of course, it requires a great deal of popularity which has some indie groups stepping away from the service entirely. Where's an indie to go outside of the PC realm, though?
Sony has been making a push for more indie games and have in fact just accepted Teslagrad for PSN. The game, which is still hoping to see PC release, is now also going to grace the PS3 via the PS Store. Fans of puzzle platformers should definitely look into it.
While their PSN availability is now assured, the same is not the case for Steam. If you like what you see then feel free to look to their Greenlight page for more information. Teslagrad is launching on both PC and PSN this fall.
