Thank you for your support! <3
- Tier 1 + 2 content
- Full Game when finished
So I'd assume it also gets early access.
I should probably have rephrased that.
Besides if you already gonna get the full game on release with the Lurker teir, why ask for a buying price, if you going to get it as part of your teir?
Unless you under the other teirs, or just waiting for the game without supporting. Then i can understand the question.
