Thanks a ton, balancing the brightness was tough, but I tried to make the fish standout even in the dark by giving them bright white eyes. I was going to include lights dotted around the walkways, but I ran out of time, and the sprite mask I used for the lights wasn't the greatest solution.
Thanks! Originally there was going to be a pulsing noise coming from each objective to guide the play, and more lights lining the railings, but I couldn't find the time.
