I had not started playing Astroneer until this most recent alpha. I haven't found it too difficult to get up to owning a large shuttle. Since it's my first time, I'm focusing on the experience now and having loads of fun, but I'll try to hunt for more bugs as time goes by towards the full 1.0 launch.
I would like to say that I enjoy the creative mode. Go one more step with creative mode and allow us to start on any of the planets (even any secret ones? ...) Just put a spoiler note to play creative mode at your own risk. Don't restrict anything - players can choose if they want to use it or not.
Thanks and looking forward to new discoveries and surprises in the full launch or post release. Maybe a separate hard mode in which some (creepy) fauna can chase you around and wreck parts of your base.
Also hoping for a Linux release. Cheers and take care, devs!
