Rubindeavor

Of course, Rubindeavor is an Earthbound-inspired RPG made using C and SDL. In this game you play as Ruby who has invented some cool stuff that may or may not be too powerful for the world to handle. This has turn-based combat with the twist that you (and your enemy) can block or dodge incoming attacks by timing the button press instead of relying on luck. You can play the game on your browser, or you can download the game and run it natively with less overhead.
