Bitter Sam is... well, bitter, and justifiably so. His grades are failing, he was stood up at the altar, he still lives with his mother, and now some mad scientist has kidnapped him and is lowering him down some sort of hole through the levels underneath his lab. Sam's only lifeline to the surface a thin thread that is easily snapped, forcing him to dodge dangerous obstacles as he drops deeper into the Earth. Thus is the premise of Bitter Sam, an amusing physics drop/avoidance tilt puzzler from Moon Active, which charts poor Sam's progress as he falls farther away from the sunny skies above.
