Giana Sisters: Twisted Dreams
I actually backed the Giana Sisters kickstarter when it first came out since I was a massive fan of the original game back on the commdore64 when it was a blatant Mario clone, yet a better game somehow, and nintendo forced them to stop selling it. Its kind of funny that in just 2 games they've completely evolved it, yet nintendo still do pretty much the same thing for mario over and over and over again. Specifically the 2D platformers. Anyway, brilliant game! Good luck!
