Casualties: Unknown
A downloadable game

Descend into the depths of the Target Planet's cave network to retrieve a critical piece of cargo, encountering many horrifying obstacles and problems on the way, to your character's dismay. Survival chances are near 0%—expect to die a lot along the way.
Caution and patience are greatly rewarded in the depths. Any mistake can spiral into an ugly, permanent death.
Play the tutorial before starting a run. It's good to understand some of the core mechanics before descending.
Translations are available! Language files are placed in the game's Data/Lang directory. The repo with them is located here. Note: Most translations aside from EN are unfinished, and not made by me.
This game contains scenes of violence, gore and depictions of depression and self harm.
