Thank you for the feedback!
Is the keyboard issue because WASD is different on your native layout? Accessibility is not a priority for us quite yet, but will definitely be there for the Steam early access release later this year.
We experimented with different movement speeds and decided the one in this release felt nice and chunky. You will be able to upgrade all aspects of the ships movement in the future, but there will be more automation the further you go up the tech tree. The ship and its location will become less central to the gameplay once you unlock more advanced technologies.
Save/Load is a must of course and will come.
