Everwarder is a strategy game that blends roguelite mechanics with a time-based survival concept. Players defend a crystal containing a trapped friend from procedurally-generated darkness that spawns creatures when touched. Runs begin with the crystal and energy, requiring players to decide between steady expansion and resource gathering or aggressive exploration for artifacts and structures.Enemies and player power escalate over time, with each failed run providing minerals for an upgrade tree. Procedurally generated worlds and random runs ensure varied challenges and emergent synergies between collected artifacts and unit upgrades.
