It's meant to back their new Giana Sisters game. And the game is coming with not just some graphical improvements. But with a lot of gameplay additions, that seems to make the game a whole lot more interesting and unique.

It's showing a lot of potential, for a game that originally was a Mario clone.
Since the time for backing up the project is near the end, and I thought it was cool, I'm bringing it here (nobody is paying me for that ..........unfortunately u.u )
If you want to back the project, you have a week to do so.
Visit the Kickstarter and take a look at all the new additions: http://www.kickstart...a/project-giana
