If not a game, its an interesting idea nonetheless. This is pretty cool because I hadn't heard of Moai before - after checking it out, it looks pretty amazing! I definitely want to use it for a future project.
This looks like it has some great potential to explore shape morphing as a mechanic, but unless I'm missing something, all there is is a single environment with a morphing shape and an invisible platform from which your avatar can tumble endlessly.
I'm not actually clear on what the mechanic will be. I know that it will look nice, but that's all I'm getting out of it. Will the shapes have powers? Is this a Trine sequel?
The shape morphing is nice and smooth and looks nice but it's unfortunate that a game did not come of the work.. Hopefully now that you are more familiar with Moai, you'll be able to put it to better use next competition.
Interesting morphing behavior, but that seems to be it. I made a yellow shape morph and hop - couldn't see any other commands or things to do. Cool look to the morphing, though.
Also, I was able to get a Windows version working: http://db.tt/J4G8fh6E
