This was such a treat, I love the graphics, audio, and overall idea.
A couple pieces of feedback, because otherwise I think it was great:
Flying around the map feels a bit aimless when you've destroyed almost everything in sight. Even though the non-destructible landmarks remain, the playing field starts to feel empty and it makes you wonder if you'll ever find another chip. I would consider adding a map accessed via the start or select button, or at least you might show the player a map before the game starts so they have a rough idea of where they're at when they start and the directions they need to go in.
Also, I noticed on the game page that you talk about needing to survive attacks from enemy pirate ships, but they weren't very difficult to defeat by just holding down the shoot button. I would suggest making enemies have a little more health so they take longer to defeat, as well as finding a way to prevent the player from just holding down the 'shoot' button forever, like maybe an overheating system.
Really solid jam entry!
