Every bit counts! Not only you help keeping it going but you also get your name in the game's credits and get updated about the game.

This is where you get access to major builds as well as vote for polls and give feedbacks

You get access to both major builds and pre(unstable) builds to try out, as well as a special place in the game credit

If you really wanna support with more than the past tiers do, there isn't much I can add at this point except for an even special place in the game credits
