Invite friends to Faeria

Hi everyone,

I have been recommending Faeria to quite some of my friends now and even wanted to send an invitation over steam as a birthday present. Unfortunatly I just missed the summer sale of steam and paying over 20€ is a bit much in my sence. 10 € was just fine for an early acces.
Anyway, that brought me to the point that I am missing an option to invite friends to Faeria! Maybe even with some rewards?
The main point though is that I would love to help make Faeria more popular and also play with my friends.

Is there any option that I have overseen or is something like this planed?

Best wishes
