That's so cool that this is your first time posing 3d models, i had no idea. Everything felt very expressive. My friend and I playing the game together kept laughing at how well done some of the ashley bubbles were.
I love how your creativity and ideas brought about learning so much. Definitely sounds like a lot of work, but its useful to know such a manual process, so when you automate in the future you'll have a better understanding of what needs to be done.
I used Vivaldi Browser, because my Firefox and Brave browsers are so out of date they say webgl isn't supported when it really is. My Linux OS needs an update so I can get newer browser versions XD We'll get to that one day :P
