That's a very kind compliment from you :D The full game will have plenty of questlines, more locations to discover, and many more mini-games too! The current demo is a small 15% of 1 galaxy out of 6 that you can travel to later, so it'll be huge!~
We are constantly working towards improving the flow of the game as well - as you already mentioned, it can be un-intuitive to find your way across the galaxy at the moment, and so we have upcoming features such as a non-intrusive map system (with custom markers) and so on, to improve on this aspect of the game experience :)
Please support this project by following/ wishlisting the game & drop by our discord channel to throw in your suggestions for the game :D
