Like I said on Discord, Mac version works, so have no fear of that...
The game looks sounds and feels really awesome... There is a scientific aspect that you don't get from many games and congrats for that... What lacks however is user agency... There is no end goal or any apparent reason to go through all this, however pleasing it might be... For example you could have an end goal to gather all four of the materials etc...
This could also be an awesome educational game... There is a ton of information on actual findings of real life exhibitions in the nasa web site that is gathered and is free to use...
Anyway I personally really enjoyed it and I really hope you keep working on it...
