Thanks for your input! Yeah, I was thinking that I might need some more contrast between the player and the background as well, but then I thought it would be fine because we weren't really jumping at that point. By the time we did have everything up I had entirely forgotten my plan to fix the contrast. Oops!
Also agree on the punch. Maybe if we had some sort of combo attack it would be worth it, or if you can throw a stunned opponent or something. Definitely something to think about for the future.
