If you go here
there's a big sign sayin A visual HTML5 game development tool
And if you keep going you will find that

C2 is not Game Maker and it's not MMF, if you want more exporters make yourself a plugin or wait politely for develpers to finish their work.
Last words. After spending years in klick%play (or click&create - depends on the country), MMF, MMF2 and almost two hours in GM i can say CC and C2 are two best things that could happen for amatour game developer.
