Several player-reported bugs were fixed: ESC now properly closes build menus before pausing, audio no longer screeches during mass attacks, and Steam achievements unlock correctly again. The frenzy particle system was also reworked with per-organism staggered emission, reduced counts, and improved fade timings.

Summary

This update introduces multi-threaded simulation dispatch, allowing independent subsystems and creature updates to run in parallel across worker threads with automatic core detection and graceful fallback on low-end hardware.

Several player-reported bugs were fixed

ESC now properly closes build menus before pausing, audio no longer screeches during mass attacks, and Steam achievements unlock correctly again. The frenzy particle system was also reworked with per-organism staggered emission, reduced counts, and improved fade timings.

Changes:

  1. Fixed ESC key not properly closing build menus before pausing

  2. Fixed audio screeching when many entities attack simultaneously

  3. Reworked frenzy particle system — per-organism staggered emission instead of global bursts, removed particle cap, reduced particle counts, and fixed fade timings

  4. Added multi-threaded simulation dispatch — independent subsystems now run in parallel across worker threads

  5. Threading auto-detects CPU core count and gracefully falls back to sequential on low-end hardware with a warmup grace period

  6. Added parallel creature updates with thread-safety guards for shared data

  7. Fixed race conditions in the thread pool's task dispatch

  8. Fixed Steam achievements never unlocking due to a missing stats request call
