For those who appreciated To the Moon (Freebird Games), The Mirror Lied is a pretty short adventure and it now has Linux support. What's really good to see, is that all their games on Steam now have Linux support.
More about it:
From a decade ago, by the creator of To the Moon and Finding Paradise: A 30-minute experimental adventure game about a faceless girl stuck inside a house with no door to the outside.
- A short play fitting for a single sitting.
- A lousy original soundtrack consisting of one single tune.
- An abstract experience that you hereby agree not to sue the developer for.
It's also free, so you can check it out on Steam right now.
