If you're looking for something to help pass the time, you'll be glad to hear that both Amnesia: The Dark Descent and Crashlands are currently entirely free to grab. All you have to do is head on over to the Epic Games Store pages for Amnesia and Crashlands, claim yourself a copy of each game, and you'll be good to go.
You might want to hurry, however, as time isn't exactly working in your favor. More specifically, the two games will only be free for another day, so make sure to grab them before they get replaced by the next batch.
When it comes to their quality, I can't say much about Crashlands given that I've never played it. Amnesia, on the other hand, is an absolutely brilliant game that I'd heartily recommend to anyone even remotely interested in horror games. With plenty of atmosphere and practically no jump scares, Amnesia was and still is the golden standard for horror! So turn off the light, put on your best headphones, and just get immersed into its world!
Have fun, and I'll leave you with one of the trailers for Amnesia, just to give you a better idea of what you're getting yourself into:
