I agree with what Parwotrik was saying.
Of course this is only a game and blah blah blah, but if you were in a situation where you found yourself trapped, you would need to use your available resources in any way that you could. Be it collecting water in a helmet to drink or use for other purposes, using tools as makeshift levers, even softening the ground to remove something that's stuck.
Hell, I even enjoyed the fact that you had to close the door to protect yourself.
The art may not be the best there is, and perhaps it could have been longer, but for me, the 'outside the box' thinking is what made me enjoy this game so much.
