It's cool how much you managed to get done. I can tell this was a monumental effort, good job!
I did feel a little throw of being tossed into the middle of it with no rails. The text popups helped a little bit, but they seemed to be on trigger volumes around the object that I needed to interact with. That made it hard for me to decide the proper order of operations at the start, and I had to figure it out through trial and error.
Also, I felt like the game was having an identity crisis. The parkour mechanics were cool, but I almost felt like they were more of a chore than anything when I was trying to focus on building a ship and needed to go back and forth to the consoles often. I think this has a lot of potential, but it needs some playtesting and time to cook.
Regardless, great work in the timeframe!
