Looks very interesting, thanks for posting!

Watching the video and reading the blurb, I immediately got some Panzer Dragoon vibes (a lone hero riding a flying mount, an evil empire hoarding ancient technology, biomechanical weapons, lots of airships, Moebius-influenced visual design, Celtic touches in the music), and looking at reviews, some other people have picked up on that too. But it's not a bad thing; the (solo!) developer seems to have borrowed a few parts of the franchise that they liked and run in a fairly different direction with it overall.
