This is genuinely one of the coolest and most unique concepts for a game I've ever seen, the core gameplay loop is addicting and the cargo bay mechanic is one of the coolest things I've seen. For the timespan you had to create this its insanely impressive, the only changes id make is id like a fullscreen option and the sound design was very little (which i think minimal sound design works for this game well but could still use some more). In my opinion you should definitely expand on this and make a full game out of it cause you have something great here, also if you did end up doing so i would absolutely love to make some music for the game but either way i really hope you turn this into a full game. :)
