While the two-man team plans on adding more content to the title based on feedback from the community, the initial offering is still pretty significant. Four players can team up locally to go through 90 levels and six bosses, or you can dive into one of the four competitive modes and play against some bots.
Flat Heroes' action largely entails avoiding death by dashing, clinging to walls, and using the environment to your advantage. You control a square and each level are faced with a different challenge. Sometimes it's a bunch of arrows that will follow you around. Other times it's little dots that will try to snipe you. There are over a 100 levels you can play with your friends with the occasional boss level tossed into the mix.
