elafreat I own a license but I'm also in favor of keeping the free version restrictions. Reason being is, it's a nod toward bringing new people to Construct 2. And for a short time length jam. These restrictions won't hinder experienced users much. At most it would be a mild extra layer of challenge for those users.

what are your thoughts on submission?
Post to a thread, combined or individual? Upload to arcade? maybe even try and convince Scirra to make a category for the jam, if it all works out.
