I don’t know anything about this game other than what’s in the trailer, but it reminds me a lot of Anno: Mutationem with its 2.5D pixel art style and (what appears to be) “exploration” sections completely separate from the “combat” sections. Who knows, maybe this game will have random combat encounters while also exploring, but in Anno: Mutationem those two styles were almost two separate games. You would be locked in a 2d-plane during combat but had 3d movement when exploring.

Anyway, Anno: Mutationem was a Chinese-made game; this game is Brazilian-made and takes place in Sao Paulo. If that means anything to you.
