Just wanted to add that I'm having the same problem. It looks like the character walk_left and walk_right got cut off in some frame for both char one and char two. It just looks like the char got its legs cut off.
I really like the aesthetics of this pack so I would love to be able to use it if this problem get fixed.

Hi, sorry, I don't have internet yet, but I've been checking with my phone and the issue with the side walk seems yo he more a design decision than a problem (I took off 1 pixel from the outline to make It more bouncy). That doesn't mean that It was the right decision so, as soon as I can, I'll update the animation. Meanwhile, you could delete the third and sixth frames and see if It does the trick. Sorry for the inconvenience and thanks for your support <3
