Hi! I saw your game a week ago, and was very surprised, because I was working on similar tool and even had roughly the same features. Now, though, I added color change with depth, and even managed to set up fractal rendering on zoom - it was quite a challenge! Your UI is really great and intuitive, mine isn't, but with that more chaotic patterns appear easier, and I like it that way. I hope you are interested, so here it is!
