Really interesting like tetris. I couldn't figure out how the blocks disappear and why some blocks made the colors change. But I liked the concepts! Great job!

I have revised the description. RGB colours have 3 colour components and it is about adding the colour values. As soon as red, green and blue together have a high value, the blocks disappear. Try to bring together colours that are very different from each other. You can try again with this knowledge :)
