The art and theme is strong in this submission! I agree with the other commenters: there is not enough time for players to meaningfully progress.
I would like to see some direction indicators to help guide the player away from dead ends and towards scrap metal. The minimap is nice, but it doesn't show much more than the screen. It is also typical to move from left to right in most games, so I quickly lost much of my precious time in Level 2 by going to the end of the beach instead of towards the town. Players can be directed away from dead ends by trails of scrap, clear obstacles in the wrong direction, or a big arrow if nothing else works.
From one J.C. to another, though, nicely done!
