This is a really well polished co-op experience for 2 people. You play a couple of cute robots - each player controls one robot by moving each of their legs using the left & right stick on the controller. It sounds clunky but you quickly get used to it. The animations and the sound effects are top notch. Puzzles are based on teamwork, moving together and helping each other to cross gaps or obstacles. It's cute, pretty, runs well and caused plenty of good laughs. Completed in 2 hours, but there's also 2 alternative variations of each level, and a solo mode.
