Brain Teaser😛🤪

This is an exceptionally good game compared to most games I have played in the past. This game teaches you to the think in different mindsets and to see in different perspectives and I love that. It’s a very challenging game with all sorts of twists and tons of different levels and stages which is just what I need. There are no ads or in-app purchases like in most games people play so that makes it so much easier to play the game and have fun. This game is most unlike any game I have ever played so thank you for making this great and amazing game.

Yours truly,
A fan

Chill out & exercise your brain simultaneously

Love all three quell games- this one is my favorite! No pressure except that which you can't help but put on yourself to solve each level with the least moves. Addictive, relaxing, simplistic yet challenging. Great game for those with busy lives and only snippets of time to spend working your brain, playing a game, including instant gratification. Worth every penny!

Beautiful calming game (and soundtrack)!

I actually first got Quell Reflect. The puzzle levels are challenging, but not stressful. If I truly get stumped, I can just use some of the credits accumulated to be shown the solution. Most games I play, I have to turn the sound off, as the music quickly annoys me. But the Quell series has the perfect soundtrack (and sound effects) to keep muy sound volume up throughout the game.
