There is also a restart button which allows the player to start the level from the beginning. Reception. The game received mostly positive reviews. Gamezebo gave the game 4 stars out of 5 praising the fact it was "very challenging and will satisfy hardcore puzzle fans" and that the game had "nice visuals and soundtrack" while criticizing the fact it is "very challenging and may frustrate casual puzzle fans" and has no instructions. "GameGrin" gave the game a rating  of 4.5 out of 10 saying the game "bludgeons freedom into a pulp and annihilates any semblance of player choice, denying any puzzle experimentation and making for one extremely unappealing game". "AllAgeGaming" called it "worth checking out if you like puzzle games". "Pocket Gamer" praised the fact that the game "lets you solve its puzzles at your pace".
