With the Beta happening early this month, it was likely we would hear about a N++ Steam release date shortly. Thankfully it will be sooner than later as Metanet Software announced PC gamers can play the ninja platformer August 25th.  Windows is the only supported platform at first, but it is coming to Mac and Linux. You can check out some footage of the level editor below:

The game will be 15 dollars when it launches, but you might as well bookmark their Steam page right now.
