Glimmer Trench

About this game

Pilot the Kettle down through a cracked-open cove into twilight caves, a glowing midnight garden and the abyss. Grab treasure with the magnet claw, surface beside the Gull to sell it, and buy a tougher hull, bigger tanks, a brighter lamp and better sonar.

W and S thrust, A and D turn, Space rises, Shift sinks, E pings sonar, F drops a flare and L switches the lamp off so anglerfish lose track of you. 14 missions, 10 relics, 8 logbook pages and one ship's bell. Touch controls appear on phones.
