loved it, really well done

include a opening menu
give it a story line, maybe zoom in a little
i think youll find it improves a bit

interesting game you have here...

you should have an intro and just briefly state the goal, it took me like 5 minutes staring at the initial sequence to figure out i was supposed to be doing something, and what, but this is a cool concept; i like it. you might also want to include some noob levels at the beginning so people can just wrap their heads around the concept really quick before they jump into some full-fledged levels. otherwise, good job, dude. respect.

Very nice

The game is hard in the same time simple and cool! Great job!
