I have played Submerged: Hidden Depths for a good few hours and got a pretty good impression of the game. Now I never played the predecessor, Submerged, so I come at this game completely fresh and with no pre-conceived ideas.
Upon starting it becomes clear pretty quickly that this game is about relaxation and exploration. Relaxation for you the player, and exploration for the characters you control. There are no enemies as such to fight, so you really can just sit back and chill as you play.
The game is full 3D, you play as Miku and Taku, the game chooses different characters for you, swapping between each, as you explore a sunken city, surrounded by water. There are plenty of ruins, which you can travel to on boat, you will then find yourself climbing, swinging and jumping to different areas of each building, and collecting various items, both from these buildings but also from the surrounding sea. So that might be flowers, boat parts, diaries, and also detecting all creatures and cataloguing them.
