Sorry, I fazed out there for a minute...
It looks brilliant. Seriously. I especially like the red writing at the top.
Few suggestions/tweaks:
1) Once you get to Jupiter-Sized, the camera stops zooming out, so either make it end at that point or ask Alex if you can alter how much you are allowed to zoom out.
2) The different levels are too short. I got from an atom to 1*1*1m within 30 seconds. MOAR LEVELS!
3) Colour scheme is meh. I prefer multi-coloured mountains, please.

4) The control scheme wasn't what I expected, so maybe add a quick tutorial at the beginning?
5) While I get why you kept the atoms/bacteria/cells/whatever they are from spawning outside of a certain distance from the centre (it's to save time and processing power, isn't it?), I like it when I get to go wherever I please and not have to worry about running out of bounds.
