Author's Response:
Thanks for the review!
I'm not too much of a fan of SFX, none of my games have any (but there is one that might end up with some in it this year :)).
A challenge mode was on my todo's, but yeah, I had 1 week to make a halloween game, and then it corrupt and I had to register a decompiler just to get it back, but if this didn't happen I may have had time :P.
There wasn't much wrong with this, except the fact that I rushed, maybe I'll do better next time xD.
Thanks again, for the review, Happy New Year (guess when I finally responded =P).
