What a unique entry! It's like having your own peaceful aquarium that you can modify and observe. You clearly spent some time on the mechanics—they're so cool. The fact that the background color and music change according to the colors you choose is very impressive! I also liked that, when zooming in, you could see all the life in the water cube more clearly. The browser version had some issues with audio and graphics, but as you mentioned on the project page, the downloadable version worked much better. Great execution for this relaxing game, good job!
