Probably not at all. I mean what would most users do with such source code? It won't look very readable since a lot of things would have to be done in c to match the events. It's kind of like manipulating the js of an exported project if it wasn't obfuscated.
What get's me from watching the second video is it looks like things are still have the same design they had from Klik n play.
Struck me that way too, they added some switch slidey bits (probably to appeal to touch users?) but left in the chessboard and bouncing ball defaults.
And good point with that js similarity.
