In order to beat Hotel Remorse, there are a few steps to handle before tussling with this game.

To launch the game, you must pray to Jesus Christ almighty that your computer does not have a recent graphics card. Due to issues with the UE4 version the game is running on, any newer graphics card, especially NVIDIA, will crash the game due to issues with the lighting. If your computer is oid, or still runs on Windows 8, you should be fine.

This game is incredibly scary, due to all of the reviews, obviously. You must garner the testicular fortitude before playing, or else you may accidentally press ALT+F4 while getting jumpscared.

This game's control structure is very simple, only consisting of a simple WASD for movement, and E (or clicking) for the interaction. Some doors may require interaction to open, while others may open automatically. The use of the shift key may be required at the last part of the game where you run away from your sins.

Hotel Remorse takes place in a hotel, obviously. In order to progress, you must open doors and read notes. Reading notes is the main way of storytelling and is also the main way to progress, so if you see one, then you should read it.
Other than that, just walk down hallways until you reach a note while occasionally opening doors.

In conclusion, you should probably waste your time on another game, as this game is mostly just cheap jump scares. But hey! It is free, so give it a shot!
