One of the best puzzle games I've tried. The game has no rewards for the player other than seeing the puzzles complete, learning their mechanics and exploring the island. It reminds me a lot of the game sudoku; completing a puzzle for the sake of it. Also, it doesn't have any soundtrack as far as I played, so I can put my own music in the background or straight up no music at all. It's relaxing even though the puzzles are NOT easy. It teaches you to be patient and wait for the answers to come, and they may come in the kitchen while eating dinner. It's not a game for people that play games fast, lack patience, or expect a big reward. It's a game for those that find peace, silence and isolated problems to be therapeutic. Worth game for a small demographic of players, interesting for people curious about this title, and boring for the rest.
