Yeah 2019 had a couple of mind-benders involving mazes - there are two Part 2s that I need to motivate myself to come back to because my fumbling that got me the respective Part 1 solution was useless for Part 2 (Day 18 and Day 20). Looking back at them they shouldn't be too hard, I just think that at that moment I didn't have the time to spare and never felt like coming back to them. Maybe if I'm bored between Xmas and New Year :)
