Excellent metroidania. Everything we love them for is here: backtracking, leveling and searching for skills, searching for treasures, weapons, collectibles. The atmosphere of the game is amazing. The gameplay with lore and story of Aetern Noctis is a mixture of the Dark Souls and Castlevania series.
The only negative in this game is the screen resolution. I can’t set my 1680x1050, it offers two others that don’t suit me and because of this the picture is not clear, but blurry. I ask the developer to fix this problem.

I read the reviews, the game scolded for various bugs and dampness, but wait, the game is in early access, it is written on the page and you are still notified about it when you start the game! I've played so far only an hour and a half and have not encountered any bugs. Someone didn't like the shooting, but I was pleasantly surprised her. It is quite at the level. Although I have only shot so far with a gun. Who scolds the collection of resources and crafting... Seriously? This is a survivalist, this is the essence of the game! In general, I do not understand the complaints of players.
I played solo, in the co-op until lez. The game is a mix of Raft game and the movie Snowpiercer. Graphically it looks very unpretentious, even with some kind of Cel-shaded effect, and the game is made on UE4, but okay, sorry, it's an indie game. Create your character, the choice is very poor, but it's not so important. We have a small platform, which rushes through space on rails, we can go forward, we can go backward, or stop altogether. As in Raft, while driving we collect various resources, with which we craft other resources and build workbenches, improve your future carriage. We can not fly away, because tied to the rope to its platform, there is no gravity. At intervals, will meet the station, which we investigate for weapons, recipes and resources.
There is a lot of crafting here, I even got tired when making a simple bandage. We need to do something about it, to simplify the steps.
When approaching the first station, I was impressed by the soundtrack. I thought there was some kind of danger, perhaps waiting for me to fight, such was the tension in the music, I liked it :)
In steam, the page with the game have screenshots and videos where we fight the monsters already built a train, man, it's cool, I do not know if it's all in the early access, but what I played, I liked it.

In this game will not return soon, because it is in early access, and I do not like survival in early access, as after any updates break the save or my world, have to start over. I have this experience with Rust. So I'm waiting for the full release.
Bought the game on reserve, it will obviously go up in price as soon as the full version comes out.
