This is the worst. If I’ve been overthinking something like that my entire nights rest will be disrupted, very much akin to a fever dream.

So far that’s only happened for Factorio, but Mindustry is a good contender.

I remember when I was addicted to Factorio, I could vividly "see" conveyor belts everytime I closed my eyes.

I've experienced this effect with jigsaw puzzles, Tetris, and the pedestrian paths in RC Tycoon.

For me, in college, it was Age of Empires. We'd have late-night LAN sessions with roommates and friends and when I eventually crashed into bed, my brain would continue strategizing for battles, determine necessary resources to mine, etc.

I once saw and felt myself biking when closing my eyes after riding a bicycle the whole day, so this isn't limited to computer games

I've had this experience with all of the Conceptis logic puzzle games

Oh no, it's on mobile? I just assumed it was not on mobile because it's FOSS.

My productivity karma was trending up this week. Was.

If it helps, I advise avoiding it on mobile because it makes my RSI flare up like crazy. YMMV.

Had the same happen to me, but with Into the Breach. That game is very addicting and should come with a disclaimer for this :P
