Good, but not that simple. The only bug is that if you close the app and later come back to "continue", the game makes you start from the beginning without the items you had. I guess you have to keep the app running in the background until you come back to the game.
Relaxing, not took hard, but not too easy either. Does not save automatically but if you go to settings and choose "save data" you will start where you left off next time.
Excellent An extremely enjoyable game with varied puzzles, appealing design and just tricky enough to feel smug when you've solved it.
Fun Difficulty 4 esp the water part
Short and sweet
I deleted the first impression advertisement.
