Star Fox is one of my favorite games ever, so I enjoyed playing this one! I played through the mission a few times to try different weapons. I had the most luck with dual Gatling Guns, but I'm also really biased towards Gatling Guns in general, so it could just be me.
The Devlog is very informative and I like how it talks about the struggles in creating the game: scope creep (which is something I'm battling in my project right now) and "Real Life" (which for a solo-dev means one bad event takes out your entire team until it's dealt with).
I also would have never known your ship's engines were rice-bowls without you mentioning it.
I'd be interested to see how different upgrades and weapons affect the gameplay in the future, such as having different weapon types be stronger against certain enemy types, or special weapons with limited ammo. I'm also curious to see what effect Companions would have.
Remember: "Half as far as you wanted to get" is still progress!
