Glad you think so! The ship takes a bit of getting used to, I think we just got the hang of it through so much testing. If you wanted to destroy the pillars you need to upgrade your ship by collecting the crates and resources in the water (either by shooting or driving through them)

Just to add, the initial resources are dropped by the rafts and the secondary resource is dropped by the boats 😊 It's the kind of thing we'd love to have communicated through a tutorial or something similar but due to game jam constraints we've hoped the UI and some exploring/trial & error is enough to help people discover everything they need!
