My hard drive had to be re-written a few days ago, so sadly I have lost all of my highscores in all of Binaryzoos games. I am thankfull however that i've managed to screen shots of my old highscore table.
I'll be redownloading soon because I wouldn't mind hitting 50,000.
As I've just said elsewhere, it's likely I'll be doing Echoes for the 360 next, and I'd like to include Crack as part of that as I quite enjoy it myself.
I'll have to see how much extra work it would be though. IIRC it wasn't a huge amount of extra code and no more media so it's a possibility.
