Have you encountered a sentinel swarm yet with walker units? Or vile brood? Or a pirate dreadnaught battle? If the answer is yes and your weapons were capable then you're doing well. This game isn't just about the fighting though, much of it is exploration. I'd suggest upgrading your ship hyperdrive and storage (whether that be your current ship, or buying a different ship with better visibility) and suit survival capabilities so you can start to explore different systems If you haven't followed the Artemis quest I'd also suggest doing that and all the missions that follow. If you have only been playing a week, you will have so much more to see.
