So I went back and figured it out. For anyone who's still interested:
1. Put 'Loop' first.
2. Add a number. This number decides how many loops you will perform.
3. Add your movement (the jump and arrow tiles) in a specific order. All of these movements will be looped accordingly.
After having played the game, I will say that it's a bit barebones. Doesn't feel like it ever really gets started. If there was some more depth to the movement logic, I feel like this could be a great puzzle game.
