In-game event · published 4 Sep 2026, 06:54:22 UTC

Update 1.1: Checkpoints

How they work Each task you complete will not be reverted upon death nor upon restart. Any half completed task will not be save or checkpointed. Maybe in the future I'll support steam cloud saves... Also fixed bugs regarding the water bottle / water task.
