What do you think about adding different difficulty modes, for after people have gotten the hang of the game? Maybe something along the lines of a casual(ish) mode on the one hand, and on the other a fast, plane-filled mode that is nigh impossible? Making the additional modes an unlock?
Yet another amazing game! The other posts say it all. Thank you Jiggy!
Also for those of you who didn't like the game:
1. It's not a shooter. Guns, explosions, etc. don't match the story or any other part of the game. Maybe in part 2 or 3?
2. If the game is laggy, it's not the game, it's your computer. My old one plays it fine.
3. The achievements have nothing whatsoever to do with the game itself.
