Agree that the test overall was too difficult.
A different opinion from the others is that I don't think it is a bad thing to have a test that is unfinishable.
It is fair for strategizing to be part of the contest. I feel it is a good change from the Sudoku sprints we've been having.

I think the downfall of this TVC was the lack of easy and straightforward puzzles in the test.
Nice puzzles for sure, (I enjoyed them after) but maybe not suitable for a 75 minute test.
