Thanks for catchin' it on stream! There was supposed to be an animation for the Woodblock when that instrument played, but I wasn't able to get it working in time before the deadline. I spent way more time on the music generator than the frontend, and my original plans to have this be more of a rhythm game you choose not to play turned into a virtual band that'll make new songs. I'll definitely be working on this more, and better animations is on that list - stuff like them bobbin' about a bit and some note particles.
I had no idea Sid Meier put out a music generator, and on the 3DO! I see what you mean by animations, because that's pretty nice animation they had on the instruments.
