I've used it before, on my Ludum Dare 41 game so I'm familiar with it, but I'm actually using Construct 2.
I can send you a link to a video of what I've done so far with the game, I call it "Make Haste!" at the moment :)
Would love to collaborate though, I can do a bit of everything honestly, which basically means I'm not "great" at one given thing, but decent in a few areas, but working on progressing :)
