Real fun, but interface needs work. – LightUp - Best Trivia Puzzle Game Review

Please add some way to pause a game. The harder puzzles can't always be completed in one session. Timer continues ticking even when app is not active. Also, the game very often registers a double-tap (reject square) as a single tap, which counts against the player's score. The difficulty level of the current game is not shown anywhere on the game screen. Other than these things, the game is well done and looks good. I have found that all of the puzzles can be solved using logic alone. I purchased an additional puzzle pack.
