Perfect relaxing puzzler – Quell Zen+ Review

Good visuals, progressively more-challenging puzzles, new mechanisms introduced along the way to keep things interesting. Includes soothing music. Lots and lots of unique puzzles, so, a good value. I use this to wind down before bed. Oh, and there are nice little creepy/sad story interstitials along the way.
