A bit hard to tell foreground from background. I missed the switch at first on level 3(?). Not sure how I feel about things happening off-screen, but no biggie for this IMO. Controls felt pretty good.
There are several options, like a different color, different pattern, more/less detail. In general as things fade into the background, they have more muted colors, less detail et.c. You have a slight variation today but it's quite subtle.
