Around mid April, when Kickstarter has given us the final list of backers. Kickstarter needs about 2 weeks after campaign end to sort this out.
Once we have the information we will immediately send out access to the Alpha build to backers who have chosen Alpha Crew Member or higher. We will send instructions via e-mail around mid April, stay tuned!
It will happen around 2 weeks after this Kickstarter campaign is finished and the data is locked in. We will send out a link to our backer management page where you can fill in all the necessary information for you to claim whatever rewards you are entitled to.
The game will be released on Steam and GoG at the same time, and we are looking into possible other stores besides these. The pledge rewards mention a Steam key, but you can choose a GoG key instead of the Steam key if you want.
We will support as many languages as we can. The Alpha version will only have English, but once we release officially we will localize the game to French, Italian, German, Spanish, Russian, Portuguese.
With time we will try to add even more languages.
