GAMEPLAY: Snappy, simple but allowing for strategy, and doesn't get boring too quickly. I struggled a lot in getting past the second cycle...maybe 'cause I got distracted by trying to shoot the space station, but that's neither here nor there.
VISUALS: The flat-color terrain is an odd contrast with the complex rendered spacecraft. I think I personally like it, but I can't say it's a good move. The color-coding is useful, and the UI is clear without omitting information.
AUDIO: The music ends up a little too cheery for how the narrative was presented, but space-y enough to still have me vibing along. Love the bzzts and ka-chings.
THEME: Not a very creative interpretation of 'everything is a resource', but as a resource extraction game, I can't say you failed. For a first round in a game jam, undershooting things like this is far better than overshooting and failing to produce a game, so you definitely did not fail.
