Super Smash Flash 2.

[Gaia]

Oh, I remember this. The controls on the original had pretty slippery controls from what I rembember. This was a problem with most Smash-based games because most programmers focused not on the base engine, but instead the characters. Hopefully you have learned from that.

Another issue I had with the first is that the immense style clashing and how most of the stages feel the same, and how some of them are OP'd (some characters with small characters are more often harder to hit, etc).

Of course, given the timeframe from the first and this one it seems you have covered most of these flaws. Also there seems to be a consistant issue with each character's respective art style (Project X Zone found a way around this, so you should look into that, I am doing something similar too with my current sprite project). But got the voices well set. Also there seems to be looping issues with the music as wel, plus (with the ever oh-so controversial) Mega Man's weapon ability seems very akward to properly utilize (I'm having to hold down one of the wsad keys while selecting a weapon? how does this work? It also leaves the player vunerable.)
