GAMEPLAY: I got miffed that I only learned the exact requirements after using up another one of my actions. Some dialogue also seemed misplaced--Sharkface started saying the AI's lines after a while. Scrap fishing is slow, parsing everyone's wishes takes a while, and the arcade machine seemed endless (not to mention easily cheesable by sitting still and spamming shoot). The concept's not bad, but there's definite refinement to be made.
VISUALS: I'm impressed that you've seemingly made a lot of paintings for the game--must've taken for-e-ver. The UI's a bit slapped-on--I'd personally reduce the font size and paint out some boxes to make it fit the atmosphere.
AUDIO: Groovy and space-y, I like it.
THEME: I don't really see it. The 'resources' were there, but certainly weren't 'everything'. Leaning into scrap more could be useful--maybe all the items are hashed together like the fish oil, instead of getting a navcube as an arcade prize.
