This bug is now fixed, its origin was escape code parsing while using the arrow keys: looped three times before getting the input. You can update the script to get the improved version. As I said, it is now fixed, plus the max level of disks is up to 13.

Recursion until hell freezes over.

Rust away!🤭 Actually it sounds reasonable, I guess in Rust 2D arrays are easier to work with than in Bash.

I don’t understand what you are asking, please elaborate.

You noticed correctly, I made the trade off because I wanted to have an extra disk level available (10 instead of 9), but I believe it was not worth it. I updated the script, it is now quite snappier I think, check it out if you wish, and let me know what you think.

Thanks for the feedback.
