This game is amazing! Puzzle games aren't always my thing but this is just the right sides of physics and frustration to keep me playing. Starts off really simple but becomes very clever and quite intricate at times. The mechanics take a bit of getting used to, they rarely 'click' but yet it is still really compelling and rather charming in its minamilist approach and comedy squeaks! Well worth picking up even if it goes back up in price. Have left 5 star review on App Store - thanks to the Dec for making it free. Highly recommend.
