Sorry to necro this if this pack is no longer being worked on, but I just wanted to add my support for door opening + closing animations. The big doors look awesome and I'd love to have a big boss stomp his way out of them!
It's a beautiful asset pack! I've only used it in a small game so far (https://gedig.itch.io/goblin-drop-jam) but I will definitely be using it more in the future :)
