Former Valve designer Kim Swift does first-person puzzling with a cartoonish touch. In Quantum Conundrum, you can enter warped, alternate dimensions at the touch of a button. Is something too heavy? Try the fluffy dimension, which renders objects cute and lightweight. Need more time? Try the slow-mo dimension, home to sluggish items and Nintendo's online strategy. Need the floor to be on the ceiling? There's a dimension for that too.
