Like you already saw in the trailer and the screenshots, the art style in this game is amazing I can be hours writing about that art style but you can see it by yourselves.
Now about the game itself, the first 10 minutes of the game have almost no-interaction and are like an animated short film, fortunately, a very good one.
After that 10 minutes, all changes and starts the real game.
This game is a very standard metroidvania, very challenging and with a lot of focus in platforming (relying very much in things like wall jump, double jump, and jump impulse yourself in enemies or enemies projectiles). I think the weak point in this game is the combat, it's very original but at the same time, I feel the combat erratic. If you played Aquaria, it's that kind of combat.
About the level design, it's ok, I think it tries to replicate some things from Super Metroid but with little success, for example:
It has a part when you fell in a tall pit and you need to gain abilities to return, but the game doesn't have the claustrophobic feel, so the feeling of "I want to go out of the pit" is not strong at all; and also, this game has no fast travel (very risky for a metroidvania), and tries to reduce the backtracking relying only in the level design, you can activate switches to open shortcuts and the new abilities allows you to take more shortcuts, but still it's not as good as Super Metroid in reducing the backtracking, I think it could be better with a limited fast travel(like the ones found in SOTN or Guacamelee).
Overall it's a solid metroidvania game with great art style. Buy it if you like metroidvanias and have patience for some tricky platforming sections(like Guacamelee or Super Meat Boy), and don't buy it if you expect something like Journey of don't want the game to be too challenging in platforming.
