i know it's 3 hours but
i'd like to have like a "hot-cold" way of checking if near for a star, because as what you said there is a .4% chance of finding the star, the combat is fine as it is and only real thing it could have improved is having the enemies flash when hit, overall it's fun but gets boring quick after you realize "oh god why is it so low, and why are there no indicators??"
also sound can't propagate in the vacumm of space so they didn't have to use a device to stop sound. which is kinda physically inaccurate 0/10
