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.
