Consider the above maze.
If Link could jump off the bridge, the answer would be 5. If he could not, then 9.
However, I have passed all testcases and validator both with and without this check.
The same applies to climbing a bridge (moving from low to high ground by changing direction while on the bridge).
I had the reverse issue ; I forgot to add the check for not going out of ā|ā or ā-ā perpendicularly (considering than when you are very close to the ground descending, you can just take the side step lol ; the text gives an indication for āfromā, but not for ātoā), ie. 7 for the above maze, and all was ok in the IDE samples, but not in the validator 
So if someone does not pass the last validator test, it may be this missing check 
Maybe above maze could be added to IDE tests, it solves both issues. 
^This.
It is disappointing that it was even made puzzle of the week without anyone paying any attention to posted solutions and their comments. That issue would have been mentioned there for sure - I know I commented on the JS ābestā solution that had this flaw.
Now it has a ton new solutions with the same flaw.
Aside from the above test case, I think it would be good to include one where you need to pass both above and under the same bridge as well.
Donāt worry, I said that I will rewrite a bit the puzzle after its highlight.
I have a little work now but itāll be done soon.
I always do the after-sales service on my puzzles (even if Iām not paid for them).
Coolā¦ I didnāt even know puzzle authors are able to change their puzzles or test cases after approval has passed. I wonder what happens with the already submitted wrong solutionsā¦
And BTW when I said āits disappointingā I was not referring to you but more to the CG staff that picks the puzzles of the week.
