I really just could not figure out how the Repeat function worked at all. I was getting frustrated at that because I was trying to use it in the very first level but obvious logic wasn't working so I assumed I'd learn but the little popup for the second level didn't help me understand it either.

Making understandable ux was pretty challenging, when the jam ends i'll try to fix some stuff, a debugger would be very important to add. An example of repeat use would be "repeat 2 move up end", if you did something similar and it didn't work it's probably due to a bug where you could place multiple tiles over each other. So you have more tiles but you don't see them and it leads to errors. I've fixed it but for now I can't update :/ still, thanks for playing.
