Best Flash game on NG?? Possibly...
I have never had so much fun with a game made in Flash. Sure, there were a few games which had me hooked for quite a while, but the freedom and creativity within the battles of this game makes it one of my favourites.
The graphics, although mostly black and white, were very appropriate and very well done. The sounds were a bit edgy in some parts (sometimes it lagged up for me, maybe that was the problem) and the music wasn't too extraordinary, but it certainly wasn't awful. I'd personally have preferred some hardcore rock or techno to fit with the theme of the killing.
Please make an expansion set of some sort to this game. Maybe you could add more costumes or different music options or more cheats, etc etc.
Props to you.
P.S My favourite thing to do in this game is to do the shotgun-over-the-shoulder-like-in-Army-of-Darkness move. =D
