4. A.N.N.E
A.N.N.E is the second Kickstarter success story on this list, and I promise it won't be the last — the crowdfunding website has helped many struggling developers not only get the ball rolling but also spread awareness among the community for their projects. The originally Windows-only A.N.N.E was able to meet the OS X and Linux stretch targets, but it failed to hit goals that would have brought it to other platforms. Nonetheless, Canadian developer Moise Breton decided to go ahead with a Wii U port anyway, appropriate funding level be damned!
So just what is A.N.N.E all about? What isn't it about? It's a shmup, run-and-gun shooter, non-linear platformer, and RPG all rolled into one pixelated package. You'll get to play as either the titular A.N.N.E or Number25, two robots split apart for the tragic crime of falling in love — I guess you can add "romance" to that genre salad bowl as well!
Unfortunately, we may have to wait a while for this one, as no target release window has been announced yet.
