The small squares in each of the larger squares in the grid make it hard to see the numbers in the squares. It would be a decent game except for that. I prefer a game where I don't have to squint just to see what is going on. There is no apparent need for the smaller squares, so I suggest you ditch them in the next game you release.
I had played several of the games in this series and enjoyed them. Then, the designer decided to start using a black border, on which the details are very hard to discern. They have added shapes to the colors, which is a clever idea. I have two problems with this game. The shapes are hard to see against the black border, and there does not seem to be a picture of anything after you finish the puzzle, but just a design.
Same old thing - woman goes out to find missing dad, but immediately meets man whom she invites on her trip. Male characters routinely go on quests by themselves in games. Who thinks a woman must have a man along or she can't cope? I strongly object to the monkeys being shot and, presumably, killed to get them out of the way. They could have been simply chased away. I only played for about ten minutes and quit because of the above.
Initially, this game was fun and held my interest. After excessively having to go back and forth to different areas of the game, it became quite tedious. I didn't even finish the game. With a map, it would have been more fun. Also, the skip puzzle button takes a long time to become available. Some puzzles do not have any instructions, for example, the one requiring you to make coffee. There is no journal or equivalent that gives information you have previously discovered.
