Bubble Trolls is a physic based arcade style game where the player must help a Troll travel downstream to his home via a Bubble Taxi. The player creates ripples by tapping the water to move the Bubble Taxi past a myriad of hazards and critters determined to pop the bubble and eat the Troll. Players are aided along the way with powers-ups that make the bubble harder to pop or cause it to float in the air.
