Very nice graphics and tunes.
Really looks like a fine piece of work.
first story block was huge piece of text, perhaps show in chunks or as the levels progress?
There were a LOT of meteors everywhere, making it feel and fly rather clumsy 90% of the time. (some meteors looked weird bumping as there were so many)
The bumping of firing looked somewhat odd at first, but I was finally using it to shoot around the meteors to hit the turrets.
imo the game would benefit from a little less meteors and and less fire ricocheting
