If you have played 'The Tiny Bang Story' you will know what to expect from this game. No instruction, you have to experiment and observe closely.
The 'flashing hand' mentioned is only at the very beginning to show you how to interract with things, after that you are on your own!
The clues are subtle, they require thinking and imagination. If you like that sort of thing is is brilliant, if not, don't bother.
The graphics are rather basic, not even as cute and interesting as 'The Tiny Bang Story', but that is part of the game, since you need to have a good sense of direction and there are indications if you are alert and observant.
Obviously no hidden object piles, just thinking and doing. Also, you don't need to 'pick things up' just click on them, and click where you want to use them and the action is done.
A great little game if you like that kind of reasoning.
