This was very fun. I think you're likely getting dinged from people looking at it because you bundled all of the executables into a single `.zip`.
I liked the style. The ship vs ground was a good little mechanic. I loved how the background of the ship got progressively more chaotic the further back in time you went.
I'm not at all sure what the upgrades are meant to do besides the armory. Once I unlocked the person in the room, I could just max the room without a second thought. I think with some resource tuning, variety, and a bit more RPG elements... this could be a pretty good game.
There was a bit too much text in the very beginning. I started to read it and then it just kept coming until it was a wall. I think spreading it out into smaller chunks would be helpful. I got just enough to understand "oh its outer wilds" and went from there :)
Did enjoy, linux build worked flawlessly.
