Order of the Sinking Star (store.steampowered.com)

Before we were married, my future wife and I played The Witness together on my iPad. Fond memories, hope this gets a mobile release too.

This trumps every other game in the genre. Beautifully simple concepts that compose into deep, comprehensive puzzles. The feeling of excitement after figuring something out is unmatched. It never gets too boring, nor does it get too hard (because you can just continue elsewhere and come back later).

Would genuinely recommend this game to everybody!
