The most difficult problem was the directional one because our group didn’t find the black-light marker for a long time, and then, the repeat was difficult to figure out. In our team, we split into two groups, one group figuring out the left part of the puzzle, and the other figuring out the other. I contributed to my team by helping solve the key puzzle and the directional lock. Our team had different people try the directional lock puzzle to get innovative ideas in so that we could solve it sooner.
