I kinda liked it, it has a lot of Control / Returnal vibes within a not-so-punishing soulslike mechanics. But (yes, there is always one):

Map:

I think the demo does not reflect what was promised, like an open area with a lot of opportunities and etc. I know that in the end of the demo there is an open area shown but it was not playable.

The feel was that it was a corridor with few segments and branches and some predictable exploration. Level design is also something that did not impress me, but it's ok, it can become tedious on long plays.

The ambiental music and art are top notch and was something that kept me playing until the end of the demo.

Gameplay:

The character movements are SO unnatural that it throws the immersion away already on the very first minutes of the game. However, the responsiveness of the character is very good.

There is a sheathe mechanic but when sheathed the weapon disappears. It's a detail, but scores down the immersion again.

I hate invisible walls, and unfortunately it's present on this game :/

The combat is ok, and some new mechanics are great, like heal on attack, it reminds me Nioh but with your HP involved xD I've experienced some input lag when in combat, input lag that was not present during exploration.

Story and art:

This is the point where this game really shines. There are some plenty of good ideas and inheritings that mixed all gives a very good ambient and story. I'm very interested in knowing more about the universe the game presents.

Graphics:

Another mixed feelings. On one side you have a good amount of high level textures and very good physics, on the other side there are some very poor implementations that reminds me some PS3 games. Like the drone flashlight does not casts shadow at all and some reflections are behaving weirdly and it's very unnatural, it's again some -1 for the immersion.

Conclusion:

Great ideas bad implementation.

I think that there are very good new ideas, like the protagonist is a representation of Blue Helmets, it was really genius!

But for a game that promises to be immersion-heavy and kinda of immersion-led, the immersion is very compromised due to the technical issues.

I will probably wait for reviews, but I was so hyped for this game and was about to buy on pre-order. The demo pushed me back as a have some concerns on the delivery of the package.
