Interesting game... I like the theme and your main mechanic, I found myself holding my finger up against the screen to find exactly where I'd jump, hehe.
You have a good game, but I would like to see some more meat on it's bones. More mechanics, more interesting timings, moving platforms for example? Or something even grander and/or weirder.
Still, for what it is, and how short a week really is. I still think you've made an overall good game and a good job! Hope you keep it up!
