Features very challenging puzzles. Some of the puzzles will be impossible if you play with volume off or are color blind. (If I was color blind, I would skip the game; good amount of puzzles involve ability to work with color). Try not to just look up a solution if the puzzle is too hard. Try to explore different part of the island and come back to it later. I used the screenshot feature a lot to remember some puzzles I couldn’t solve yet.

The reason why I don’t give it 5 stars is because some of the puzzles just seem like trial and error until you get what it’s trying to do. For example, puzzle 1 is simple to understand. But puzzle 2 or 3 could add a new element to the puzzle that makes it harder (but it’s not easy to guess). This game has lots of Easter eggs and I had a good time.
