The boat takes ten seconds and I think I was a little harsh with my time constraints; happens when you get used to the difficulty of your own game
The shortest time it takes to beat the game is 4:30 seconds, and the total time allowed is 5:00, so that would have been something to improve on for me
And a lot of people have mentioned the rain; making the loop longer would have resulted in it not being night time when the rain started, allowing for a significantly easier time when getting out of the cave.
