Yeah good point about the logo and level restart timings - I can definitely reduce those by quite a bit. The issue with adding a "Next Level" button is that the Story missions are not all sequential, with some optional missions that are branches along the main mission path. The other issue is that sometimes the story map has an event (after a specific mission is completed) that triggers stuff. So maybe I can force the player back to the main map when the there are multiple mission branches or if an event mission is completed.
With regards to the inability to steer in open space. I could definitely make a mention of this to the player in the first mission (tutorial), but I think it becomes quite clear that its a core mechanical limit as you play the game. I will think about adding an indicator or effect to the ship... but something this demo didn't have was items/abilities yet - there are abilities you can unlock later that will allow you to steer in space for limited amounts of time.
Thanks for the review, and best of luck with devving!
