Speedrun video games

excerpt from the description:

This TAS is an improvement of 3:01 over the older 11:55 TAS by ClumsyDoomer from 2017. It is the result of 490 (we made a point of counting) hours of work spanning 1 year, 10 months, and 15 days. However, we made the decision to not count the hours spent running brute forces long enough to walk away from our computers, and so only counted the hours spent “actively working on the run”. It also does not count quite a bit of time spent with routing and experimenting with test maps. Taking into account all of that, the time taken would probably be around 600 hours.
