This was a neat concept. A pattern on the background ot indicate what you were moving would be nice, and the rate of fire on the cannon is pretty slow, making the game play somewhat tedious.

Firing rate was a bit slow, other than that, good job... Doesn't work on IE, btw...

neat with a pure javascript game!

OK, there's two games here called "Rotate" and this one I'm more likely to be able to play...

I'm not judging this (yet) but I have to say this:

Congratulations for making a javascript game which runs at a good framerate.

Runs very smoothly for me, well done.

Very innovative, I'd like to see a faster pace and maybe some sound or more effect when I win or lose to make it more dramatic.

Since you can rotate fast, and the bullets are slow, it doesn't seem to matter which way you are facing when you fire as long as you rotate with the bullet in the air. Not knowing when you will actually fire doesn't help either.

Still, interesting concept and brownie points for making it with only dynamic HTML :)

Interesting concept. A bit confusing with how the cannon is supposed to fire, and firing is way to slow.

As others said, the firing rate is too low, and some sound would have been nice.

On the plus side, it ran smoothly under Firefox/Linux, and moving the world to harm enemies while keeping "good" entities unharmed at the same time is a good idea that could be improved upon... not necessarily in a circle.

Would have been nice to see a word or two by the author too :).

It's hard for me to really see the gun as an enemy. Also, it seems very very slow paced. And it was difficult on Hard, but I guess that's what I get. Can't really complain about that.

Cool idea, but the fire rate made me snooze.
