i already reported the bugs with the hunger/sleeping but i'll post my other thoughts here for so other people can reference them if they agree/disagree with them
first off, the game is pretty big, sitting at a solid *2 gigs* unzipped! i assume the textures are the main culprit, but i think you can reduce them all to 512 and less without issue due to the camera distance
when assigning work priorities, it would be nice to have some indication of whos good at what in the work-assignment window. rimworld has the same issue, where id have to pause the game, then go back and forth for every character to know 'ok this one is good at construction so they get construction priority set to 2 and everything else to 5'. it's not that big of an issue for 3 peons, but if i had to do it for 10 i'd kms
id assume most people who play this would be familiar with the genre. i know i was. first thing i did was pause and scout around for resources (burgers and meds in this case) since i assume it would be similar to how rimworld begins, with your ship crashed and cargo scattered around everywhere.
while it's still a WIP, you could edit the first message you get (that talks about survival) to give a hint for any newbies that there's food available to haul. players not familiar with the genre would get insta-filtered, i'd say. rimworld-likes already have a scary onboarding process with all the menus and submenus. if it was up to me, id have a pre-build 4x4 wooden house (just walls and a door) as a 'your colonists took initiative, now its up to you to tell them what to do next' sort of deal
i'll play it again once the non-eating bug is fixed but this was just stuff off the top of my head!
once you get this sorted out you'll have a GMI game on your hands.
