If you surrender to the primal regression, your character get corrupted. I recently added a story arc that allow you to continue playing after that so it’s not really a Game Over scenario as Demoness_Kiss just said. However, this story arc is early access and WIP (like the whole game actually)
Anyway, the best way to get a general idea of the game is to try it yourself
