Refunct is a very peaceful and simple first-person platformer where you're not really guided by anything but your senses, it's odd, yet refreshing. It also throwns in some Parkour – because why not.
You are literally thrown into the game as soon as you load it, without any kind of explanation and tutorial to guide you.
Style wise it is rather simple, but it's quite beautiful and calming at the same time and it's a fun experience.
It even had some really great lighting going on with the sun actually moving around!
So I have three free keys to existing Linux gamers, first come first served to those who are logged in (you won't see them if you aren't logged in):
You must be logged in to see this section!
If you don't manage to get a key, don't fear! It's super duper cheap on Steam at £1.99 and it's on sale for a few days too so it's even cheaper right now!
