This was really well done! Excellent visuals, sound design, and very well polished. I really loved the background music!
My only feedback is that I wasn't so sure what to do with the black hole. They didn't really specify what they wanted, but maybe I was missing something. Just kidding! I replayed the game, figured it out, and got all orders perfect :)
Very well done! I can easily see an expanded version of this being on Steam as one of those cozy, comfy games with a cute art style.
