That's quite the backstory to this...

My keyboard doesn't have an 'Any' key so I couldn't start the game...

Ok, being serious now.  That was pretty cool.  It was really easy though, that's fine it is just a demo level so I'm not overly concerned there.

I laughed when I finally noticed that my guy was t-posing the whole time and it was actually really funny that the boss was too.

Overall, I think leaning into the 'shitpost energy' would be my recommendation.  It's your call of course, but I liked it.

I am very unfamiliar with your origin story for the game, although I did find it interesting lol.  Going in blind and just commenting on what was in the build it seems like a solid start, the game plays well and I didn't notice any bugs or major issues.  And I really feel like the UI was well implemented, I always find that part to be kind of a slog to get through so it's nice to see an indie developer take the time to put some thought into it.  I really loved star fox growing up so overall I had a great time playing, even when I was intimidated by the bosses dominating T-pose lol.  

Really the only thing holding you back here is the recycled assets (and I can sympathize, my primary skillset is in the 3D art pipeline and there is a ton of stuff to learn in order to create custom assets).  Nice game though, fun to play and I could see it expanding quite a bit.
