Switch, a puzzle platformer by Scott Addelsee, Jemma Barnard, Kate Fierek, and Tom Saunders, is like Sonic CD, if it were designed by the team that made LIMBO. You'll be switching between the past, present, and future to collect keys. Moody atmosphere and clever puzzles are hampered by wonky jump physics and unnecessary "switch" limits, but Switch is a game well worth your time.
