I'm typically not the one to bash products and developments, but there is something that needs to be addressed.
Construct (be it 2 or 3) has this tendency to implement platforms up until the point where the most important thing comes in: the monetization. Then it stops right there.
This is a major problem (in my humble opinion). The facebook instant stuff is nice, it's good to have and all, but why would one NOT implement the monetization options of the API? It is the single most important thing. If it was me, it'd be "monetization first". No initial release without the one thing that enables users to recuperate their investments. IAP, Admob etc seem to have always been on the ass-end of development, and with the release of the instant games object in beta r91 it's the same.
It should be the other way around.
Make it the No.1 priority.
