Hello everyone,
ːsteamfacepalmːAs of right now the price/download button is missing for many new games being released on Steam. Sadly this game has been hit with this issue. I have contacted Steam Support as well as other developers experiencing this issue. Hopefully I can get it resolved soon.
In the meantime The Endless Empty is also available on itch.io
