Looks really nice, very impressive achievement! May I suggest trying to use softer colors? Perhaps more grey shades with some colorful accents would get the message across while at the same time being easier on the eyes

I'm well aware of that, just like I am well aware of all the limitations with displaying multiple colors simultaneously. What I am suggesting is that you might choose a milder color palette, perhaps also using sprites for color accents where they are needed. In general using light grey, grey and dark grey for backgrounds and geometries can be quite a bit nicer on the eyes than, say, a solid yellow background, while still looking quite slick
