Nice atmosphere, graphic is old school, but ok.
The difficulty go very hard suddenly. I just spent 1.5 hour on one impossible puzzle. nearly impossible
I like the way you progress, the variation on the gameplay
No walkthrought too (I hate when you need that to finish a game).
Just one word came to mind playing it : frustration ...
And the average session indicate is half hour...
I don't particularly recommend this game, despite his great ideas, the peaceably ambience, the difficulty is sometimes too hard for me.
3/5 stars :)
