I haven't attempted to make art yet, and this is kind of art, so I guess it is my first art project! It's very simple. Just click. You can also press space to toggle light and dark. If you start from high enough, it will do an extra mini jump. The entire engine is just one script. Even though this is such a simple engine, you can make some really cool art with it.
Everything is by me. This is only 143 blocks >:) but it still took me a while.
