I don't often write serious reviews, but I feel this game deserves one.

Gameplay
It's a game about flying where you only indirectly control your craft, which happens to be a really cool giant falcon. Or it can be a pterosaur or a dragon.
You're armed with various kinds of laser-like weapons and will dogfight against other flying opponents, ships, flying ships, giant things hard to categorize, and even flying fortresses. You will learn to line your shots while managing your bird's energy and health, and you will feel really badass doing so.

Progression
You, as in the person in relative control of the flying beast, are expandable. You will pick a new character at every new chapter, which you can, oddly, play in any order. Don't fret, everything important that you unlocked at any time stays unlocked (birds, locations, missions, upgrades, etc.), so you can restart a chapter with a new class at any point without losing any progression. It seems a bit weird at first glance, when every other game has convoluted unlock trees and grind, but this freedom is actually very enjoyable.

Narration
The scenario is pretty elaborate, and more than serviceable, with a complex lore about factions and houses waging wars, forging alliances and betraying each other in an enigmatic world full of ancient secrets.
It should be noted that EVERY line in the game gets voice acting, which is even pretty good !! My favorite until now is a drunk character that is pretty funny, as in an obvious imitation of someone grossly drunk.
The side missions are pretty forgetable (mostly combat or escort missions) but they have the merit to exist as additionnal content.

World building
The game world also benefits from some escort mission that are diegetically integrated into it in the form of ships that will ask for assistance or mention that the waters are dangerous, and in general the world feels alive, with ships crossing trade routes, odd pirate encounters, and hostile factions, depending of the chapter.

However the game succesfully avoids the "theme park effect" that some open world games have by offering vast expanses of oceans to cross. it has in general a sort of eerie feel to it, especially in some areas like the Temple of Creation which I found completely by chance and was a pretty amazing moment.

Art direction
It is somewhat "simple" on the technical side (low poly, limited texturing) but every piece fits together with the others really well, to create a beautiful world that feels a bit out of time, or rather "after the times" : it feels that civilisations have already ran their best course, and all is left is an endless ocean of lost knowledge. From what we can gather from npc dialogue their life is hard, and conditions dire for most, which I feel is also conveyed through the somber tones of the cities and the sea. In general the color palette is beautitul, with surprisingly superb combinations of colors for the ocean (deep purple, cyan blue). YMMV, my screen has weird color balancing.

In conclusion
If I'm not mistaken this game comes from a very small dev team, which can explain the quirkiness of the game sometimes. I feel that also contributes to its odd charm though, and it should be noted that performance is incredible (some AAA should take note) and is perfectly stable. I'm really interested to see this studio's next projects.
