Several errors have been corrected:
The character would get stuck between the access doors to the lower part of level -1, and couldn't get out. Now, death by entrapment has been implemented, allowing you to continue playing afterwards.
The Walkie-Talkie could not be placed in the trays of the metal detector arch, but now it can be.
When entering the level code to access level -1 directly from the main menu, the six-digit limit was not applied, and the player could enter infinite digits; this has also been corrected.
A writing error in the Walkie-Talkie conversation has been fixed, and now the text matches the voice.
The selection circle on screen has been fixed; it no longer appears in the start menu.
We hope these improvements and corrections enhance your gaming experience.
Thanks to "Alexmeownwn" for their suggestions and reports.
