The dotted pattern on the background textures brings a really unique look to the art. I knew there must be some established name for this kind of close-up printing pattern so I looked it up. Apparently, these are called "Ben Day dots". I assumed this was a comic book invention but according to Wikipedia, it was developed way back in 1879! Suffice to say, you'd be justified in calling these graphics "old school". :)
Gameplay wise, it felt a bit off to only be able to shoot enemy bullets and not the ships themselves. With this limitation in place, I never really felt like I had a good way to protect my cargo tail beyond one or two crates.
I like the "ghost ride the ship" idea. It would be interesting to explore more complex platform options in the future. The ones in the game pretty much let you get back on your ship whenever. One can imagine larger, more complex platforms and maze-like structures that really put the pressure on to decide whether to take the risk or stay onboard.
