Amazing as usual! Somehow each Quell game is better than the last. The new mechanics introduced in Quell: Zen make the puzzles even more challenging and improve on an already great concept. After completing all the levels in perfect moves, I still have to find all the jewels. And do the zen stone levels. And do the black hole levels. This game is hours and hours of fun. Highly recommended!
Best game ever. Challenging but enough help if really stumped. So many different challenges; completing level, completing in minimum moves, find secret locations and gems and stones. Great!
Another excellent Quell game. The puzzles are excellent, the story is engaging. The only thing I'm not keen on are the controls when multiple drops are present - it's too easy to inadvertently move an unintended drop.
Horrible development This game has erased all of my data TWICE in the past two days. I haven't even been able to complete the fame because of how data-glitchy this game is. I want a refund
Great game. Just the right level of challenge and a little story to keep you moving along and absolutely no annoying ads - which really is Zen these days. All the Quell games are winners. Thanks for creating them.
Another great Quell game from FallTreeGames. This one's about as long as Memento and Reflect combined, and has equally wonderful and elegant puzzles. Highly-recommended.
