I love this game
This game is fantastic. I love the story (it's almost a novel!), the art, the characters, the originality of some weapons, the many upgrades, the level design with obstacles, the level details, the length of the game, the different detailed endings, and the replayibility with new game plus. I've been playing this game for days, and while not playing it I was often thinking about the pirates in their space station :).
Small suggestions for improvements:
The ability to replay older story sequences, or at the very least replay the last one, in case you accidently pressed skip.
Make a sound or some other effect that makes it more obvious when overdrive is fully charged (more obvious than the little red bar in the corner).
Make the character talking in the cafe a bit more complex. Only rarely are there more than two characters in there, so making a choice who to talk to is almost never needed, which makes it somewhat simplistic...
I didn't earn the special ending yet and didn't try hard mode so far, man I've still got a lot of work to do! :)
