This is really neat! I found the rotate too sensitive and I would have liked a list of controls just to make sure I wasn't missing anything, but apart from that, very cool! Especially liked the use of colour.
Thanks! Good points, I added the controls here (and might look into the settings for turning, though I kind of like the swiftness).
The color palettes are such a huge part of the experience in this austere style, it was super interesting to test different moods for the areas.
