In this game, you will be taking control of a small boat and exploring the ocean, looking for your missing grandfather. You will need to navigate through the ocean, avoiding the different obstacles that are in your way.

Along the way, you will have to solve different puzzles and brain teasers, in order to proceed to the next level. Some of the puzzles will be easy to solve, while others will be very difficult.

The more you solve, the more points you will earn. You can use your points to buy different items in the shop, such as new weapons, new boats, or new tools.
