This is THE best game on newgrounds, surely. I mean my goodness, this is some of the best it turned out. However, If I may make a few nitpicks...
It seems like the game had an ABSURD amount of bias for the pico series. I understand that he's popular, and trust me when I say the characters play REALLY WELL (Especially Piconjo, he's just...awesome in this game), But I still think you could've included characters from maybe A DIFFERENT SERIES IN THEIR PLACE. Piconjo is pretty much necessary, I guess, But then Nene could've been switched for some other female character on newgrounds, and I honestly HATE playing Convict to no end, so...Yeah.
But that's just my nitpicking, the atmospheres are still awesome, the characters are still who they are, and every single one of them plays great (EXCEPT FOR CONVICT, GYAH, I HATE PLAYING HIM)
