I really recommend this game and Haiku Games' other games too.
The concept of each game and each chapter is well-made. You could challenge yourself to improve your thinking, then solve some puzzles.
This game has a lot of different themes to play with. Whether it be a Mystery type or an Adventure type, or even a Survival type.
Graphics, sounds, storyline, and puzzles are top-notch. If you haven't played this game yet, play it now. You'd be hooked!
It requires internet connection for downloading per chapter, but you can play it offline.
Oh, by the way, if you already finished all of the games, don't uninstall it. You can either play it again or wait for their next game update. They will release more games there. So just wait.
P.S. They have different games also not just in this app
