Caveboy Escape (iOS) • ★★★★☆ • I downloaded this game somewhat on a whim, without any recommendation, and then expected it to be terrible. Instead, I played through all the levels and then spent way too much time in survival mode. It's calming, almost. The goal is to get the caveboy through each level, but you can only pass through tiles in groups of three of the same color. The time pressure makes a not *TOO* challenging puzzle fun.
