The two I'd say would have the most impact are #6 and #10. Being able to pause the game and being able to save the game while playing will prevent a lot of potential frustration. If possible, having the game auto-save when you visit a planet could be useful, too.
I see. We will discuss, and probably implement pausing again.
I'm pretty sure it does autosave when you enter a planet... there should be a some indication to the user :/ ... my bad.
This just in! - I've also added a task to put an autosave logo when we autosave. :D
