Starfish in a Hot Air Baloon
In this kit your goal is to program the starfish to fly his hot air balloon. You can be as creative as you like, but the blocks you'll find inside will allow you to make the starfish:
1. Go up as long as the space bar is pressed.
2. Fall slowly to earth if the space bar is not pressed.
3. Look happy when he goes up, scared when falling, and bored when he lands.
I took a long time experimenting with different ways of making gravity and got myself nice and confused with variables and all kinds of acceleration - but I kept trying to simplify things, and this is what I came to. Remix away. I also made a solution to match the goals above, but there is no "right answer."
