I really like this game, couldn't work out the controls at first but once I got the hang of it it was pretty dope.
There are a couple of things I'd like in it but wouldn't make any significant change to it, they're simply preferences:
Since once you've decreased your speed you can increase it again an infinite number of times it follows that you've got infinite thrustability (Not a word, for sure) so you should really be able to keep increasing your speed forever. I'd like to to do. To control a 100000000u/s spacecat is my dream.
Also the angle cap, once you're completely vertical you can't pitch up any further, which means you can't do many cool aerial maneuvers, which is a shame because aerial maneuver spacecat is my other dream.
Easiest game ever, hands down. Phantom was obviously a hacker so I got rid of him the same way mods do - Beat the hell out of him. The moving eyeball on the title screen was a nice touch :P
All badges unlocked on my first playthrough. Luckily there wasn't an "All achievements" badge, since I didn't get the 'die with less than 10,000' achievement and, because of that, the 'get all achievements to silver' achievement - Would have needed two plays, maybe three D:
