I've created Unpuzzle as a calming experience for all players to enjoy. Good difficulty and learning curves guarantee a way to teach you to play without annoying tutorials. There are no time limits no punishments for mistakes no wrong solutions and there always is a way to proceed. And yet 10 additional mechanics provide enough challenge even for puzzle fans as they are combined. So if you feel stuck - use a hint skip the level or just close the game take a break and continue from where you left off once you are ready.
