Really impressive work for a week! It also gave me strong FTL vibes. I struggled to understand the consequences for my choices, though. I added guns, but ended up shooting much slower as a result, and didn't see an obvious way to control the fire-rate. As a result, I just made the thinnest ship I could with two guns, so the shop rarely provided me with anything I wanted. The a cappella soundtrack was great, though!
Congrats to the team for your first GWJ submission. This shows a lot of promise!
