We did talk about having an animation for charging the jump, but I didn't know how I would go about doing that while also allowing the player to move. If you were moving while any animation other than the running animation was playing you would look like you were sliding around.
I suppose another way we could have done it is to stop the player from moving while they charge their jump, play the animation, and then give the jump a move horizontal push as well. I do think that doing this would have resulted in making the game much harder and more frustrating to play though
