We apologise for the delayed feedback:
I think your interpretation of the theme was unique, but I don't know how thoroughly it links to the theme. As you say "the player embodies a space station with a death ray", in my opinion this makes you not the weapon but the facility that holds the weapon. But skipping past that the game was fun to play. It was extremely slow at the start of the game, it took a lot of time to get through to customisation options and upgrades, but that is only really an issue when judging a Game Jam with time contraints. One of the major issues I had with the game was the laser sound, it was constant and very grating. And there was no way to turn it down from the game so i had to adjust my system settings to be able to continue playing the game. It would be great to see a settings menu/option for customising things like sound and sensitivity.
The GDD contained a lot of good information, but it would great to see it further fleshed out with more information around your ideas and introduction.
Overall this was a fun game to play. Thank you for entering it into the Game Jam!
