Holy hell this is an impressive collection! Really, my only complaint is how the "hide menu" button doesn't seem to work as the interface takes up so much space even when in browser fullscreen. Thankfully, you've added a zoom and pan feature!
I don't like the zoom feature, it glitches on mobile and so when I accidentally zoomed out, I couldn't zoom back in, and eventually I lost the animation from it going too far out of my screen.
