Definitely more could be done to champion the games that show off the really amazing things Construct is capable of: there's a list somewhere of C2-developed games that have been Greenlit on Steam or are awaiting it, which would be a good place to start.
I made a collection on Steam of games made with C2 - http://steamcommunity.com/sharedfiles/f ... =103535227
While some Construct 2 games are still waiting to be Greenlit and some have been Greenlit but not yet released, there are a handful that have been released.
The C2 games released on Steam are:
Epic Space
An infinite universe MMO currently in Early Access

Angvik
A platform action game set in a joyful but unforgiving land.

Our Darker Purpose

There is also a post here on the forums that lists these games as well as games released on Desura.
