"One of the highest quality puzzle games we've seen." – PocketGamer "The visual design and imagination of the game are stunning, with great attention to detail, and the sound effects are downright enticing." – Adrenaline Vault "A masterpiece visually, as well with the actual gameplay." – AppAdvice INVENTOR MODE Starting with simple puzzles, players are introduced to the widgets that are used to build machines — gears, pipes, balloons, chimes, hammers, wheels, props, and more.
