It was finished some time ago but needed polishing and balancing. Now it’s complete and has been added to the beta version of the game. It works as follows:
A warning appears.
The anomaly is activated. It remains active for 8 seconds, during which most of the light sources in the level are disabled.
The player's flashlight is automatically enabled, allowing for limited visibility.
Chance to appear: 30%.
The anomaly is deactivated.
It starts appearing from level 3 onward. So level 3 has two anomaly types that can occur multiple times per level, with a 30-second interval between them.
I'm always looking for feedback, so if you're interested - join the playtest and share your opinion.
