In fact, it was A=B who encouraged me to develop this game. I also received encouragement from Artless after releasing this DEMO. I even wrote something to thank Artless Games in my game (the Steam verison).
The copy problem should be related to browser permissions. The bug behaves differently across environments. However, since I can no longer build an HTML release due to the use of desktop-only functions, I won't be fixing this bug anymore. But the final release of the desktop version will work as expected.
Hard core players like you may want to chanllenge the shortest length. But they will challenge theirselves even after implementing a better solution than the author.
But non hard core players may suffer from poor experience from strict challenges. So I set those challenges only by adding flexible numbers (from 6 to 10 as I remembered) to my solution except the tutorial levels.
If you mean the "pages" on the right side, That's used for the '!' subprogress instruction. But yes, I do think the current subprocess implementation is not good enough. Maybe I will change to other designs, or even remove it.
------
Section 5 requires the use of nested loopings. People new to Brainfuck always stuck at calculating multiplying. Multiply is simply performing additions many times. But adding in Brainfuck will simply destroy the origin number. So what you should do is to keep a copy of it.
------
Section 7 reqiuires the use of looping as condition statements. It may be a little more difficult than the problems before. But once you get that point, you will have ideas to solve them.
I agree with you if you are writing an command line interpretor for brainfuck. But this is a game.
Maybe I am taking the game "Human Resource Machine" into consideration. That's weird when I produced an output as expected but the game did not finished.
