I don't really use the boost mechanic at all. Only at the beginning of the missions to get to the enemies quicker. I also completed level 1 without getting hit (once, it took a few tries, I'm not the best at video games), but I didn't really sue the boost to escape enemies or similar actions.
As I previously said, the rule of cool is a cornerstone of (nearly) every sci-fi story. But I think an interplanetary civilisation would be keen on being efficient (if it actually is is another conversation entirely).
Tungsten rods have been use in multiple sci-fi stories already, in my opinion they're no more unique than a space laser. I'm not really sure what other options there are, but I would definitely like at least some kind of bombardment ability, regardless of if it's an orbital bombardment or aerial bombardment. I'm sure Mezz can come up with an idea that satisfies him.
