This has been out for a couple of months but here's my first Construct 3 game on Steam:
Yafti
Yafti hasn't done as well as some of my other games (maybe should have spent some more time putting some polish on it), but it was fun to make. It includes a level editor.
So far I have 6 games on Steam, three made with Construct 2, one with Construct 3, two with Unity.
