Here I am quite disapointing that I cannot rate your game on the design. You did an ammazing job with the ship and the smugs !
The idea is very original (I was really curious when you posted screenshots on the discord) and it works well.
The fuel is well adjusted. decrease slowly enough for you to explore, but you also have to check for the precious refueling items. Maybe decreasing the fuel when just rotating the ship wasn't necessary, as I felt less inclined to exploire and sometimes just went in a straight line.
Oh, and I don't know if there is an end screen, here :/ Did you have time to implement and end goal ? In the description, it implied that there might be, but never found it :p
