Most of the time save over my old 5:40 came just from much cleaner execution and greater use of the mouse, I did also apply some new command optimizations though. The 4:59 had a bad ending, so it's not surprising I saved a bunch there. Feels fairly decent now, there were still some clear mistakes and slowdowns but this is a tricky run.

Played in version 1.001.000 (the only version with zips) in DOSBox 0.74. (Running in QuanVM might be faster, but I'm still on the fence about allowing it.)
