Control were WASD, and mouse/left click to move the arm, but as i said in a previous comment, we had some problem with arm physics.
The base goal was to have a container full of crate/stuff (A lot, to stress the player) that you could move/push/reorganize with your arm, in order to struggle accessing the oxygen. But it seems like we didn't quite make it to our goal :D
Hope you enjoyed anyway, and thanks for the input. :)
