Submachine is another entry in the crowded "escape the room" genre. Well-made, won't stump most players too much and very little pixel hunting compared to other games with similar objectives.
Only complaint is perhaps it's a tad short. Plenty of other flash games on the
site as well.
Submachine walkthrough can be found under comments.
