played it for a few minutes, am stuck already

Okay, purchased the game today at Epic(pitty it isnt available at Steam). Noticed some stuff like, when starting a new game, the customize button is the one whit the next functionality. Also, i noticed there isnt a big galaxy overview map like in the old games. Will it be available?

And last, how get i go to a bext turn? The space doesnt work.

thank you
