Hi! This project is not quite a game. You can watch it though! The part that the colors appeared to be "erased" can be seen in another way... Click "1" to see how the "erasing" process work. You can switch back by pressing "2". If you can not click "1" or "2" or you didn't understand how the "erasing" part work, I can tell you. The background is black, so when I "erase" it, I actually just color the part that appeared to be "erased" black. When you press "1" the background changed and you can see the black better. Hope you enjoy it! Why did you scroll down here? Still scrolling? Well you reached the end. Since you scrolled down here, click the space key. Then press "1". You can later press the left arrow or the right arrow. You can try it while it is still drawing. The circle will look like it is moving.
I used some codes from @JimmyC and I got the idea there. Thanks! Also, the title is similar to a candy I think in Willy Wonka and the Chocolate Factory (The book)
