It definitely seems like playing as Brownie can give players bad habits. I wonder if that was intended by design. "Yeah, you can double jump, but you'll be gimping yourself in the long run" seems like a real Contra-ass thing to do.
Also I'm kind of blown away that after soloing Deadeye Joe in the Forest, Vinny felt like changing characters. That would have solidified Sheena as the choice for me.
