I came back to this mission because i was unsatisfied with my former time. After studying my old run and looking for alternative pathings, i found a slightly quicker route. While practicing, i got the perfect bossfight, resulting in a new record. I am still unsatisfied with the mistakes i made... Hopefully i can get a cleaner run in the future.
