This is great. I laughed out loud when I discovered that notes you throw upward off the screen eventually come back down if you throw them straight up. Definitely getting my toddler to play with this. I have two suggestions: one is a tool/mode that lets you remove a bunch of stuff quickly, and the other is a simple undo mechanism. Since there isn't much instruction, you need to explore by touching, and e.g. when you're testing to see if a three finger gesture does something, you tend to create a lot of unwanted notes and potentially accidentally remove stuff that you overwrite.
