The current official update adds an optional experimental Adaptive Difficulty setting. It is off by default and can be changed under Game > Game Settings > Adaptive Difficulty.

- Difficulty adjustments relax toward standard balance when the player's performance changes
- Night Mode can become harder but is never made easier by the system
- The initial experimental version has no on-screen adjustment indicator
