Currently the game is in pre-alpha and there is no playable version for us at this time. Here is a link to give you an idea where things are at. Hope it helps and welcome to the community.

You will have to wait for a while.
It will take a while for SBS to create the game, because SBS is a small studio. They are planning to release Alpha 1 version soon (6 months later...), but only a few people will be able to play it to begin with... They are going to be probably testing the game and such.
If you are planning to play the game in the alpha 2 version you need to buy the alpha 2 access Or you can upgrade your pledge to proprietor, because proprietor already has an access to the alpha 2.
