- Be careful for the size of the ball and where you place the image when creating the sprite costume in the edit pane.
-I'm still not quite sure how to make a block after you give it a name and decide what type of block it is --> I just realized you can drag blocks from the sprite script area to the build your own block pane.... this could use more instructions in the interface...
- Pseudocode, and test out code in pieces, then combine --> even though SNAP is visual, viewing how code is nested is not easy.  In fact for a visual language the design of that could be way more helpful
-I assume using "broadcast" is like return. I havent used it yet. I just used the poor practice of creating global variables
