A waste
Ok, first of all, you say that this flash took you a long time to make. That was your first mistake. You put too much effort into this flash and you didn't get enough of a reward. This was below average. The graphics sucked big time, and there was little to no plot apart from "Kazuki" running towards the bad guy, while his lackeys get their shit repossessed. The most interesting/only interesting thing was the animated boobies in the flashbacks, and the music. This is/was not deserving of frontpage status. Things like the Xombie series, Bitey of Brackenwood and Prowlies at the River, and to a lesser extent(but not much) Foamy, have the quality that you should be aiming for.
Just remember that you don't need to be violent or brutal(not that I'm against those) to be funny or successful. Originality is what makes people laugh, cry or whatever your goal happens to be. Take "Dad's Home" for example. Awesome graphics, funny, original and i bet it didn't take half as long as yours. If you're going to put as much effort into a single project, as you claim you have on this one, make sure that it is one of the higher end submissions on this site. Good try though.
