Thanks for playing!
I'm really happy you liked the library encounter, that was one of my favourite enemy encounters to setup! I now also see some ways it could've been done better, but I'm happy it has a little variety compared to other fights.
As for the movement yeah I've been wanting to try queuing movement actions for the player controller but have lacked either the time patience to implement it. Maybe next year!
The humanoid model I got from here: https://comp3interactive.itch.io/low-poly-human-mesh, the animations I got from mixamo and the textures I made myself. I've been using that model asset for several games now and I think they work quite well.
