I often play Chronom with a very casual attitude, mindlessly pushing back the creeper while watching TV, often with arbitrary limitations put on myself. I usually play with no drones, often I put the city in a difficult starting position rather than an optimal one just for fun, or restrict other buildings as well.
Today I had a day off and was playing in the morning and stepped away from my computer for something, thinking I had paused it. I ended up getting called away further and had a super busy afternoon and evening, not getting home until after midnight. I then discovered my game was still going on double speed and my base was still alive.
The map was February 13th 2023. I ended up with a score of 376 and a time of 1535 min 44 sec.
It is undoubtably my worst score by a massive margin.
I fell asleep once with the game still running. Woke up hours later to a 3-digit score. I don't think I submitted it, just started over.
I never do drones, and the game for me isn't over until I have eradicated all creeper and capped all emitters. That explains why I'm usually near the bottom of the scores list. ;)
