Hi! I'm sorry but right now I'm moving to a different apartment and I only have internet access through the phone, so I my apologies if I can't address the issues right now. But to answer your concerns:
I will check the first issue as fast as I can.
The second one is because It was the workflow that other developers I've worked with used, It was meant to represent the char jumping while running, but I see your point.
Anyway, thanks a lot for the detailed feedback :D, It helps me tons and I hope you can find a use for the packs even through this problems. I plan to update/rework a bit the older packs at some point and animations are first on the list.
