Took about a week to learn the game comfortably whilst playing 10-12 hours per day. It took another 3 days to pull off a WR run that I was satisfied with. All in all it can of course still be improved, perfect play is always a thing, which the video itself is not. With more optimization, more RNG, and more riskier strategies, the time could in theory be shaved off by another 2 minutes at most, making it sub 1h2min. Although this is not a feat easily accomplished and would've taken a very, very long time to achieve (if even possible). That being said, a time sub 1h is simply impossible to improve by plain gameplay means, unless something else is discovered. Thank you for watching.

Special thanks to Sciku for helping me learn this game and answering all my endless questions, thoughts and not-so-occasional rants.
