From Private Test Build to Live

Before releasing Winter Nights publicly, the event went through a limited Private Test Build phase with our Game Tester community. Thanks to their reports and feedback, several improvements and refinements have been made before going live:

  • Improved Winter Crystal spawn locations to prevent edge-cases where they spawned too close to walls.

  • Adjusted ambience and lighting in the Winter Lobby based on tester feedback for better mood and performance.

  • Fixed additional Icy Room collisions discovered during the test phase.

  • Refined Winter Lobby menu music transitions to prevent audio clipping.

  • Improved clarity of energy tracking inside the Event Dashboard.

  • Fixed several minor UI issues that testers spotted during event preview.

  • Additional optimizations and balance tweaks informed by tester gameplay sessions.

  • Decreased the Number of Winter Crystals that spawn in Level 0

  • Decreased the required Amount of Winter Crystals to 65 (was 100)

A huge thank you to everyone who participated in the testing phase! Your help ensured a smoother and more polished launch for all players.

Known Issues

  • Shader compiling may still take longer during the first startup (normal behavior).

  • Fatal Error may occure when loading new Levels (still under investigation)
