Hot Fix : 3-1 stage, Door bug

We’ve applied a small hotfix to improve gameplay flow and address a progression issue in Stage 3-1.

🔧 Changes

• Added an additional floor in the middle of Stage 3-1 to slightly reduce overall difficulty and smooth out pacing.
• Fixed an issue where doors could fail to open. Now, doors will automatically unlock within 20 seconds after entering a room.

⚠️ Note on Door Issue
The current fix is a temporary workaround. We are still investigating the root cause of the door bug, and will replace this solution with a more stable fix once a better approach is found.

Thank you for your continued feedback and support.
