I got this email from Luke earlier in the week, he's the one that created the SDK. Hopefully we will see something from the FGL guys soon.
"Hi Ed,
Thanks, and sorry for not getting back to your last mail over the weekend.
I've currently been pulled off of this project for a few days (bad timing) because some other really high-priority tasks came up, but I will be back on it soon. When I next work on this I'll make sure to look more deeply into the Construct 2 stuff, because it does seem that a lot of the submitted games are created with that.
I'll keep you in the loop when I make any progress on this."
