There is this 5-min long parkour sequence in Star Wars Jedi Survivor with only a couple of checkpoints. It took me two days of trying to make it all the way through and I nearly lost my damn mind in the process, but I finally did it.
I need a long nap now.
@quietphysicist I had a similar experience trying to get PowerShell to do something I could do in Bash with my eyes closed. Yours sounds like more fun.
