Hello Space Mechanics!

It’s here -Space Mechanic Simulator – Prologue Playtests are now open. We hope, you are as excited as we are. We have made every effort to make the new version of the game more interesting, complete, and better in any way. We’ll be very happy to hear from you on our Discord and Steam about your first impressions, things you would like us to change, features you like, and stuff you didn’t like so much.

Playtests goal?
