Maybe it's fixed?

Several bug fixes have been made. If there is no problem, we will continue to sell it because the big bug have been solved by chance. The stage for driving by car has also been revived. We apologize for any inconvenience this first release may have caused you. Please restart the STEAM application and update the game.

PS: Currently, we are checking the phenomenon that the corpse of an enemy character jumps when the menu screen is closed at a religious institution.
