Maxwell's puzzling demon v1.5.22
[h3]Levels update[/h3]
- Replaced B-N with a new puzzle.
- Reworked B-13 again, as many preferred the appearance (the question mark-shaped levels) before the change in v.1.5.16. The level is now a bit harder
- Fixed 9-22? to prevent an unintended solution.
- Adjusted 5-17? considering difficulty.
