Well, I enjoyed MMN, so...
Great job in making another Megaman Flash game.
1) Graphics- I can see you're using Megaman Extreme sprites for Gameboy Color. I kinda like them more than normal Megaman sprites for Gameboy. Though still crude, the background is better compared to those of Megaman Next. The cutscenes are fine, if not for some part when Zero's face looks mishapen(How come Megaman gets the muscle body more than X?:P)
2) Style- As it still unfinished, I gives style a 5 as I still haven't see any originality except in programing. Supposed having Elvis Jackripper as a robot boss, or a swine-riding Sigma in the finished game?:P
3) Sound- Some megaman musics, some Legends of Mana musics and the Castlevania: Symphony of the Night Boss music. All are my favourite. But I will prefer hearing Megaman music in Megaman game.:)
4) Violence- Seeing you hammering a Maverick. That's brutal.:D
5) Interactivity- Apart from the Megaman Next's feature, X get to climb the wall, dashing, climb ladder and a maximum of 3 selectable characters. Sweet.
6) Humor- Seeing you hammering that Maverick. It doesn't stand a chance.:D
Overall= I notice that X and Delia can only do 4% damage to the boss per attack(Charged X-Buster for X) while Zero can combo slash and does more than 4%. So far it is good. Just hope you'll finish it sooner. Oh yes, do add more chest-bursting Maverick.:F
BTW, I am new to Flash and am trying to brew up some platformers but don't know where to get the tutorial needed(The one Macromedia gives along with the Flash only teaches you how to use their tools.:_).
