Looks like they're using the same UI library thing that Construct does (thought heavily modified), but that's about it. Apart from that, just about any game making tool (MMF, Game Maker, Stencyl?!?, etc...) is going to have similar looking features... layout window, object bar, properties bar, and event list of some kind, etc.
I downloaded one of the videos and their event system seems to be unnecessarily complex. It looks kind of like Game Maker's event system, where you create blocks of code for each object, rather than a top-down script sort of format like Construct. Still, it's an interesting looking project.
