The first playthrough I think I completed the game in about 3.5 hours. (I had seen another person solve some of the puzzles so it wasn't completely unknown to me.) Last night I did another casual #SegmentedRun and got about 1h30m. (I just watched Parhelion's 39m23s run, and wow.) I don't think I'll ever #speedrun it at that level, but it would be nice to get under 1h. #LimboGame
