I am glad you like the concept and presentation. And I do see how repeating the intro could get grating after a bit. It was initially for the sake of this explanation I had in my head for how the system works but I didn't consider how that would feel from a gameplay perspective. I do plan on creating a post jam version with slight tweaks to how everything works.
As for the part with the numbers yeah that was completely on me. It did originally allow for you to use numbers but for whatever reason I removed that functionality. I honestly don't remember what my reasoning at the time for it was lol.
