Just now got this comment on main by @StackMeter
This is a very good challenge, apart from one thing - help mode is FAR too overpowered. I could take +, * and h (in Python), and write the password as chr(1+1+1.....) +chr(1+1+1.....) and write all of the characters that way, using multiplication to ease the process. Though, without it, I think this becomes a very interesting challenge, especially for languages like Befunge-98/<><, which would be unable to do as such. An idea would be to ban +/*, or add a penalty for using it, though I'm just throwing ideas around at this point, so take my up…
