the game is literally unplayable to me because of an irremovable add in the middle of the screen

Really well made puzzle game. Some neat tricks, and made you stop and think about what needed to happen. Lots of fun in a small package, I would love to see more like this

Good puzzle games unlike most others , have logical reason for any action you do. ( Including the result that comes out of it )

That was pretty great! Took me a while but I now know your tricks!

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.
