Hi, I understand your frustration, and I'm truly sorry that the asset pack did not meet your expectations. Let me clarify a few things that might help:
Not all of the characters in the pack are meant to be playable—some are enemies, which is why they have more limited animations. Additionally, this pack is a work in progress, and I am committed to adding more animations in future updates.
Regarding the price discrepancy, I'm not sure why you were charged more, but I recommend contacting Itch.io support to help resolve this issue.
