We came across these two tweets from PixelProspector of interest
15 Games that were created with Construct 2 (or Construct Classic)

We found our way to this following this dude called Richard Davey "@PhotonStorm" he's also doing some very cool stuff in html 5.
Anyways, just a quick share, feel free to chime in with any references, resources or developments for platformers with C2.
