Pretty well made in terms of visuals, audio and gameplay, and nice that you thought of more players than just Windows users.
Nineties: I guess being this zoomed-in was a way to avoid having to draw much on screen per frame, but I’d probably have preferred seeing a bit more space around the ship. The graphics seem low-poly enough that being able to see a bit further away from the ship.
Fun: It was fun to play for a while, but doing the same thing over and over did get repetitive after a while. Also, it seems you can survive for quite a while, so being able to save the game and continue later would be nice, or at least being able to pause the game if you want to walk away from the computer for a short while.
Also, at some point I got a mission that told me to go to the place where I already was, so that was a quick mission to do. Also, the game seemed a bit zoomed-in: it’s hard to dodge an obstacle you can’t see coming until it suddenly hits you from behind.
Sound: the music fits both the nineties and the game style and setting. And the sound effects make it pretty obvious when you hit (or get hit by) asteroids. If you want to add more sounds, I think sounds for getting cargo and creds might be a nice addition, but not really necessary.
UI: The arrow was useful (although I think games in the nineties tended to avoid such arrows due to a patent which I think has since expired; I think that situation led to some games using minimaps instead) and I can read the mission descriptions when I get missions. I also saw that when I clicked the button after getting a mission, trying to “end the cutscene”, I got “we don’t need that here”.
Marketing: The logo looks nice although I would personally have preferred it to have a slightly bigger font (but with the white text on the pretty dark background, it’s still fairly readable). The logline (“You’re needed in space. Do your part for the system.”) seems fine, it doesn’t say which type of task the player is needed for in space, but with the thumbnail showing one ship flying away from something and a couple of asteroids, I could mostly figure out (however, it’s not obvious what the ship and the station is doing, it’s not even obvious that the station is a stationary thing and not a UFO that’s moving around.
The game page seems fairly complete (and also, it says that it’s about hauling cargo). Only thing I found a bit harder to see were the hyperlinks, especially those in the “More information” section, perhaps they could be darker or bolder.
