Rollie is a new NES game by the guy under nickname Optomon/Optovania. He is the creator of The Guardian Legend: Secret Edition. And also a number of nice mods. Now he created his very own game from scratch.
He started a kickstarter company here: https://www.kickstarter.com/projects/optovania/rollie-a-new-game-for-the-classic-nintendo-nes
So you can back the project right now if you want. Or wait when kickstarter campaign ends.
