Cute idea. No idea how long it goes (I assume forever) but I upgraded guy output to ~100. One of my guys managed to die of thirst despite the room being full of water, but seemed like a million chance event.
The audio mixing is only thing that really annoyed me. The sound effects when you grab and ungrab are weirdly loud.
