Battle of Olympus (オリュンポスの戦い) improved by 3:33, after more than 8 months had passed since Jackic's last version.
This improvement consists of many minor optimizations. The biggest improvement (timewise) is because of the new way that the hero (Orpheus) collects the 60 olives, which are required in order to buy the ocarina.
People often compare this game with Zelda 2 because of its similar gameplay.
While playing, Arc discovered that it is possible to break the normal collection sequence for the 3 fragments of love. Unfortunately, this sequence breaking does not result in a faster TAS, and so it does not appear in the movie. For a detailed explanation of the sequence break and its problems, see this forum thread.
