I was pretty fast two days ago, because I reached The End of Time when the clock hit 03:00 hours, and this includes getting all the treasure on the way.
Yesterday I repaired the Masamune for Frog and gave it to him in five IRL-hours.
This evening I want to restart the game and do some really serious perfect-game-speed-running, but I won't be able to finish it before I'll have to go to bed, because I work tomorrow.

I can't even enjoy the game as much as I have time for tonight, because it feels anticlimactic to quit the game when I know I can finish it in one go.
