This is amazingly well realised given 96 hours! The grimy visuals and the way you interact with your environment makes it feel very physical and tactile. I also really liked the sound FX and mixing, it may be my mind playing tricks on me but I like the detail of the furnace playing a sound effect when full! Overall the gameplay and presentation marry well to achieve that feeling of long stretches of mundanity broken up by emergencies in a cold world.
I only have minor issues: the collision seems a bit finicky and there was one time I got stuck on the pipes and had to restart (could extend collision above them or just remove their collision), and there wasn't good feedback on the brake lever. I wasn't even entirely sure which position was 'on' or 'off' haha, just needs a sound effect and some screen shake.
