Remember N+? It wasn't as celebrated as Super Meat Boy or as widely debated as Braid, but I liked it. I like all stupidly difficult platformers with a sense of weight and style. N+ had both in spades and the sequel -- N++ -- looks a little bit bananas.
No idea when the game is coming out. The team is currently in the process of squashing bugs, but is fairly confident the game can be submitted for certification. The plan is to release the game on PS4 shortly afterwards. Almost certainly we'll be able to play it before the end of the year.
Metanet Software, the team behind the game, has released a ton of footage in the meantime, which is useful for me personally -- I wasn't even aware a sequel was in the works.
It looks good. Actually, a better description might be this: it sounds good. The music in these trailers is pretty spectacular and has me sold on the game more than the game itself.
Honestly, this soundtrack is absolutely badass and I'm super keen to hear more.
(And also play the game.)
