Resolution above 480p? Keyboard controls...?

Is it just me or the music sound way off?

For some reason, there is no text where it seems it should be during gameplay. Same with tutorial messages. I'm just getting blank dialogue boxes when characters talk too, including their name. Relaunching demo does nothing, but before first play I did try various resolutions and modes, which may resulted in this behavior....

I have noticed a couple of in-game references to other Astro Port games like Vulkaiser and Vulvehicles. But I have not played all of them, so what are others I may have missed? What is the ship at the very end that assists you?

The trailer’s chorus on the store sounds like music by Grendizer/Goldrake. Some chords are obviously identical
