Thank you so much for your feedback!
Well, I think is quite obvious that we might have aimed for a few things far greater then we could actually achieve in so little time, which, ironically, somewhat reflects that narrative aspect you just mentioned. We had some ideas for the narrative, unfortunately, we didn't have time to properly work any of them into the game, which also can be said about shopping and going to new areas with the ship, and that's why the printer-shop and the cockpit aren't working.
As for the floating debris, I'm not sure if you are talking about the visuals or the design of it, so I'll answer both.
They were made to give some amount of direction to the player, just so you don't go place to place aimlessly, but since we were in a bit of a rush, I ended up failing on giving it enough of purpose, shape, or challenge. I did want to give it some variation rather than "Another rock, but this time, blue", as well as tweaking the sprites to better fit the tilemap. We ran out of time...
We plan on continuing to work on this project, so we will definitely take critiques into account.
Thanks again.
