Reporting in to mention that I 100%ed the game. The speedrun portion was very tough to perfect, though.
Good job!
So the time challenge was the hardest for you?
I only managed to beat it by four minutes. It took a long time to properly plan out and perfect the route, and dying even once meant that it was a hopeless attempt.
I see. Which character did you use?
Sorceress. Mystic Tome and Radiant Pearl made the difference in the successful run.
