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.
