You can now write games for Firefly Zero in #C or #Cpp!
C is a language with a huge #gamedev ecosystem. It has lots of famous retro games (like DOOM), emulators for retro game consoles, and interpretes for languages like Lua. And all of that now can be ported to Firefly Zero! Surprise us.

Now, bootstrapping your first app in any language supported by Firefly Zero is just one command:

Oh, and we're now working on SDKs for a few more languages. The first one will be announced very-very soon. Stay tuned ;)
