Libra - Thanks for pointing that out. I really should have checked it still compiles after changing the function name for consistency with the name of the event it is going to handle.
Don't use the fast forward button if you want to do well on this game - you actually get slightly worse results when fast forwarding than when playing at normal speed.
I fail to see why there is so much fuss about kreds on this game. You can complete all 5 tracks on hard without any of the optional extras that you have to pay for.
It's obviously not original but it is certainly not stolen - this is entirely my own work. Anyway, thanks to those of you who gave it a half decent rating.
It's not a rip off, it's my loving tribute to the greatest arcade game of all time ;)
It may be lacking in originality, but I don't think it's too bad for my first attempt at games development in Flash.
