I have no idea how to draw a background effectively. I've always had Great Barrier Reef in the back of my head, but there's a big chance it might disturb the player. Image 1, solid blue: This is about as basic as we get it. As we can see, this doesn't disturb gameplay at all, but it also removes any feeling of depth and adventure. Image 2, deep blue (2 colors): This is basically what I had before, and this is honestly what has worked best until now. it gives a slight depth, and it doesn't disturb gameplay. Image 3, Great Barrier Reef colors: Sort of but not really an attempt at barrier reef colors. I picked some colors from there just to quickly test how it feels in game. It wasn't as noisy in game as I thought it would be, and it's probably going to be less noisy when I actually draw something, not just... blobs. Super Mario Bros 3 uses a clear blue background, and a darker blue + almost black as background elements. This works like a charm, but I don't know how I can effectively use this in Akiro. Another game I'd like to draw inspiration from is Braid. Somehow, with all those colors, they still managed to separate the background from the foreground. That should be my goal. Maybe I could draw great barrier reef inspired background, and put a blue 50% layer over and see how it works out.
