Posting on the N++ NeoGAF thread, Raigan Burns posted that tough platform game was being ported to Steam using a new programmer Metanet brought on about a month ago.
There are still a few more months of work — we want to add all of the planned post-launch-update stuff that got put on hold when our team imploded — but we will definitely be bringing N++ to Steam. We’re still looking at other platforms too.
Raigan also mentions the recent patch for N++ that went up on February 3rd. Apparently in some situations the “evil ninjas are invisible,” making a few levels impossible. He apologizes for the bug and hopes to have a new patch up in one or two weeks time. N++ is currently only available on the PlayStation 4.
