Hi Lucy!
Envious of the progress your teams made with your proof of concept. Taking advantage of resources online, like a player controller, is something we've been doing with ours, and it's been working great.
I'm very curious to see how this VTuber reaction system. Maybe it sounds more complex than it actually is, but I'd love to see some sort of adaptive mechanism for expressing player performance, kind of like the Doomguy's face in Doom
Best of luck to you and your team!
