Safe Zones are side chambers along the walls of the well, sealed behind a time-field: while the player stands inside, everything outside freezes.

Each Safe Zone contains either a treasure spot — a gem vein or a crate holding a gun module — or a Shop (marked by a hanging sign above the bubble). Roughly half of side rooms are shops, with three exceptions: Arm Spin Style drops the chance to 1 in 7, Levitate Style guarantees the last side room of a level is a shop, and the Member's Card upgrade makes a shop appear on every floor.

Landing in a Safe Zone does not end the current combo. Time only stops outside the field: dropped gems and corpses in the well still fade while the player is inside.
