My mom recently got this game for me and it’s a great game for both of us to play. There is a water droplet (which is very fragile, of course) and you have to navigate it through a series of mazes and collect the pearls in the smallest number of moves possible. There are also spikes and switches and other things. There is a tutorial that explains very easily about the different levels and obstacles.
I would recommend this game to anyone who loves to think while playing!
