If you want to be part of Ship Miner’s Steam Playtest, you can join by pressing the button at https://store.steampowered.com/app/3113690/Ship_Miner/ that looks like this:
I will add more and more testers overtime. If you request access and get the chance to be part of this Playtest, please also join Discord and/or fill the Feedback Form from within the game, your opinion means a lot, and will help me making the best possible game I can.
By the way, if you join the Discord and write to me I could also give you a Playtest key directly to be sure you have access to the game.
For Playtesters
Already joined the Playtest and want to be in the latest unstable build? (probably full of bugs)
