Oh, nicely done! You beat the game faster than I could remind myself of the cheat code!

You're absolutely right about the colors. Right now, the color-blocks only show what would happen to the wavelength (which gets 'black' as you head into UV), not the brightness. There are so many effects, which can get confusing if all presented at the same time, so I had to pick and choose which I'd represent.

That said, I really should have added levels that dealt with the brightness. It's a cool effect, too, dammit! I'll keep that in mind.

About the doors, if you're noticing what I think you're noticing, a quick explanation... Put shortly: in their rest frame, they open/shut simultaneously. But to the moving raptor, those 'simultaneous' moments happen at different times. Which is why the raptor feels like she can fit through a pair of doors that are otherwise too close together - there is a period of time (in her frame) that the doors are both open, letting her through.
