Super Mega Runners 8 Bit Mario is a 2D endless runner that uses the aesthetics of the classic Super Mario Bros for NES. The main character in this case is not Mario, though, but a pixelated version of Abraham Lincoln. You can also unlock other characters, like pixelated versions of Mr. T, Napoleon, and Daft Punk.
The gameplay combines common elements from other endless runners as well as other Mario games. The main character runs nonstop in a straight line, from left to right, and your goal is to jump all the obstacles and try to get as many coins as you can.
In Super Mega Runners 8 Bit Mario, how far you jump is determined by how long you keep your finger pressed on the screen: the longer you hold down, the farther you go. You have to take this into account and try not to fall into holes while landing on the bad guys' heads.
Super Mega Runners 8 Bit Mario is a great endless runner and platformer that's not only appealing for the nostalgia factor. The game itself is really fun and offers a lot of content, including different unlockable characters, enemies, power-ups, etc.
