A lot of potential
This game has a lot of potential to be something great. Perhaps they could name it somewhere in a distant future Super Smash Bros Melee that it has so much potential (lol)! I'm trying to say something positive before I say something negative to be a good critique-er...although it would feel like I would just be telling you to be more like SSBM.
I guess the only real critique I have for you is the enemy AI needs a touch up. I stood next to a cliff and watched everyone kamikaze'd off of it LOL. I'm tellins ya. This game has real high potential. All you have to do is program the AI to be more advanced...although I'm sure that probably would take a bazillion hours and maybe even a College degree or something to do it like the pros. But I do believe ya did what you could and to me, that's what's important about making a Flash. Do what ya can and the rest is out of your hands...sounds cheesy and it is! :) have a nice day
