While I haven't played N++ I've probably spent over a hundred hours with its predecessor during the many repetitive lessons back in my high school "IT" class. It was a simple game with easy to understand controls and a difficulty hump so massive you needed climbing gear to get over it.
But overall it was an immensely fun experience so I'm glad I can tell you that the much improved and sadly PS4 exclusive N++ will be making its way to Steam later this year. While not officially announced just yet the co-founder of Metanet Software, Raigan Burns, said on NeoGaf that they are currently working on porting the game to Steam.
Here's the full message:
"The good news: we've found a new programmer, and they've been working on porting N++ to Steam for the past month or so. 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.
Anyway, thanks for your continued support... and please keep letting us know if you find any new bugs.
Raigan"
If you know nothing about N++ its best explained as a fast-paced action platformer where you have to use your wits, reflexes and anything else you can get a hold of to get through the hundreds of extremely challenging levels. As I mentioned before you can easily spend over a hundred hours on the "N" series and come out of it with sweat underneath your brow and a smile on your face.
Besides general improvements, new levels, obstacles and enemies the biggest feature of N++ is the addition of a co-op and competitive mode so you can join up with a friend and try to solve the more difficult levels that way. Everything is easier when you have a nice fat meat-wall in front of you to block those pesky rockets.
There is no official release date, or even announcement, for the PC version of N++ right now but expect to see it later this year given the context of the message above. Finally, here's the gameplay trailer so you too can see why N++ is well worth keeping an eye out for:
