Have not played this myself but seems like a fun game! It also has a Metacritic user score of 7.5 which is fair!

*** Don't forget TCB/Quidco.

Blurbs (very long one):

Kromaia is a six degrees of freedom adventure shooter which takes action, speed, agility and immersion to a new level. Insane enemy patterns and swarms, giant god-like guardians, ancient temples, contraptions and treasures, visual ecstasy... All in a vast and unexplored universe only ruled by physic laws. What if the coin-op machines golden age started today, adding complex maneuverability abilities, encouraging spatial awareness, as well as an A.I. adapting to the way you play? Here is the chance to know.

The Worlds

Kromaia takes place in a multiverse and tells the story of a stranded soul who awakens in a weird shrine, finding itself sealed inside a mechanical unit. Having no memories at all, it must make its way in search for answers, in a world of forgotten devices and hostile creatures, while a somehow familiar voice within claims to know its mind better than itself.

The Challenge

Is it still possible to make something different set in outer space? We do think so. For that reason, you will not find in Kromaia slow movement, ships maneuvering like planes or boats, nor endless steering pursuits in circles, but a completely different approach. Our navigation system is entirely driven by physical forces, a different set of thrusters is arranged for each ship in order to maximize maneuverability: Fluid displacement for novices and, for experts, impossible turns and extreme dodging, combined with a powerful multidirectional boost system that allows moving over the real speed of sound in any way you can imagine.

Forget all the vehicles you have already controlled like aircrafts, rockets, choppers or traditional spaceships, think of all of their capabilities available at the same time at the tip of your fingers. Besides, Kromaia features a special kind of emergent gameplay: Here we will use the word "procedural" for something different than just randomly generated worlds. The advanced A.I. system in Kromaia uses physical parameters and a sophisticated prediction model to adapt units speed, attacks, flocking and smart group formations to the actions you take during your quest. The results: the game experience is different every time depending on the way you play.
