Challenger's Sleep

Challenger's Sleep is a deep sea Vertical Scroller that pulls you down from the bright Sunlight Zone and into the Sohm Abyssal Plain - and then deeper still. Featuring beautiful 2D art, simple controls, and a gripping mystery, we can learn what lays at the bottom... or stay sleeping below the waves.
