The Flat mode of this DLC has also been abandoned and is also extremely buggy like the base game
It has the same settings problems that base game has and also has it's own problems
The lever that resets your power in 'danger keep out' randomly gets stuck and starts freaking out. the duration it's stuck for is random
beating 'danger keep out' in almost entirely LUCK. it depends on how long the buggy power lever get's stuck for.

Don't purchase this game if you plan on playing in flat mode (non-VR)
this game and been abandoned and extremely buggy for 5 years now
An Extremely persistent and long lasting bug is one where your settings reset once you launch the game. and trying to fix them in the settings menu will soft-lock you in the settings menu. the settings sliders and buttons are very buggy and feel like they are fighting to work against you, even if you manage to change a setting you can't save it or back out because the confirmation button is also broken. (The default settings are also awful with extremely low sensitivity, extremely low brightness, no subtitles, and max graphic quality.) The only solution I've found is to delete the entire game every time you're done playing and reinstall it when you wish to play again.
