For the people saying the animation is not practical, didn't most of you tell him to make it look like the hammer is heavy? So when he makes it less heavy you guys say its unrealistic and yet when he makes it heavy you say its impractical. Make up your minds you are confusing the poor boy. Personally Tuna,
when I look at your walk I think more of a lock on type thing(though that doesn't work well in a 2D game) I'm on the side of the fence that thinks you should make it practical and less realistic. If you are going to have dashing, keep the run, scrap the walk unless it serves a very noticeable purpose.
Quick question, what program do you use to animate?
