Frogatto & Friends is an old-school 2D platformer game, starring a certain quixotic frog.
It's a big adventure with all the classic fun - you fight monsters, collect coins, talk to people, and buy new stuff. Also, frogatto has a very flexible game engine.
Frogatto is an open-source platformer or jump-and-run game, which means you’re given a cross-section view into the world, and you help a small green fellow named Frogatto walk and jump between solid footholds without getting hurt.
There’s a long history to the genre, so just by being in it we inevitably have a lot in common with other games, however, we’re not trying to clone any specific game.
