> MonoGame is a free C# framework used by game developers to make games for multiple platforms and other systems.
I'm really not a fan of C#, to be honest. But maybe next year goodwebgame (Rust library) will be stable enough that I'm willing to use it in a gamejam, because then it'd work both in HTML5 *and* natively. (Last years entry used quicksilver, which is *okay*, but it had some weird issues that I needed to essentially work around in code)
Also, SFML is actually cross platform, if you don't need mobile & online :]
