Published	Title	Build
24 Jun 2026, 17:06 UTC	Update 2026-06-24 Performance improvement Now the framerate should be more stable with a nice balance between CPU and GPU workload Eventual stutters can be still present Expect issues as this game is still under development and the content/behaviour may differ from the final version.	23896564
