Thanks for the video! At the very least, you tried to reach the second ending. Regarding the door bug, I’ll address it in the update, which is coming soon.
All good! I noticed this bug from the very beginning, but I didn’t think anyone would open the door in a such way. The bug has been already fixed and won’t occur in the next game update. Regarding your attempt to evade the enemy, you simply had to wait for it to finish its pathway. Then you could have proceeded without any issues!
