I'm glad you enjoyed the game. If you're referring to the "mental" bar as the "durability" bar, then yes, it’s a game over (bad ending) if it reaches 0%. However, to prevent players from encountering a sudden bad ending while unsaved progress, I’ve put some safety restrictions for durability so it doesn’t easily drop below 0% in Part 1. In later parts, I plan to introduce various bad endings while also removing the safety restrictions. I'm not entirely sure if I understood your inquiry correctly, but I hope this helps.
