Hello @CodeaNoob. If you edit your comment above to put the whole of the code for each program between a single pair of ‘fences’, that will make it easier for others to copy and paste your code into Codea.

Actually there are 2 different programs here. One is an arrow pointing down due to gravity and the other is a bunch of colored blocks falling.
