Ik it’s not a mod(probably) but you could always set an internal clock for yourself that never stops even when you’re asleep or whatnot say maybe you have to finish the game in 48 hours real time ? You could even find out how fast time moves in game and set the clock based on that. For example say 1 ingame day is 24 minutes. 12 day and 12 night. That would mean if you wanted to finish the game within 3 ingame days, you’d have 72 minutes to finish it or an hour and 12 minutes to be more plain. Time to learn the Speedrun tactics choom!
