excellent puzzle game

very good presentation, flwaless execution and design, a lot of puzzles that get more challenging. i think the dev did a good job with this app. a must for puzzle fans.

It’s ok, but...

Decent game, though the UI is a little awkward. It doesn't have any twisted thermometers like print versions of this puzzle, only straight lines. Too bad, because the twists are cool.
