The most beautiful puzzle plus action game ever. You enter a lonely but beautiful world of mazes, water and what not! The best part of it is, that it is a first-person simulator game.
And this is a paid version and the original version of the game. You can try the free but incomplete game first from the play store.
In this version, you can play in three different modes- Day time, Nighttime, and Rainy Day.
Hope you enjoy the game!
