Hi Oco, nice assets! I'm using all your medieval fantasy ones to make a small game :)
I've been using your sprite sheets but some of the frames are spaced/aligned very weirdly. For example, the jump animation for the character seems to move in the X direction and in the Y. I think this is trying to capture the jump height, but most of the times it easier to program it so the sprite stays in place (like your run animation).
Lastly, it would be a lot easier if instead of uploading strips of frames of the animation, you could upload the frames as individual numbered images in separate folders. This would make them a lot easier to use.
Thanks
