ok, ive watched it had a piss and here goes...
right , for a first flash it wasn't that bad but...
YOU'VE GOT A SHED LOAD of things to work on
firstly, up the frame rate, the action was a little too slow pased,
also Frame by frame some areas, as i noticed that the majority of this was tweened, (Even Krinkles when he does his madness series uses frame by frame animation)
next, work on sounds, a lack of music, (not in the opening but during the area where the main action is supposd to be) is a HUGE mistake,
work on your art a little, i mean... there like.. orbs and shit but you gotta put a little bit more effort into them, add some highlights, tweak it a little, add shadows, gun flares and smoke to make it look a million times better ^^
overall, your improving so heres where you score
Graphics - 4/10
improve by adding highlight as stated above (also add some blood!)
Originality - 2/10
its JUST ANOTHER MADNESS CLONE (you did say however you were inspired by madness) and there's not really anything that sets itself apart from the hundreds of other fash movies that are just like it,
Sound - 5/10
working sound effects and music in the opening credits + voice acting (but you GOTTA add some music in the action scenes)
Style - 6/10
Madness (ish) backgrounds and coloured characters
Overall - 6/10
and its a generous 6 out of 10, work on the areas above and the score wil just start climbing
