Hiii, I've made a video about the game and wanted to give you some feedback about it, hopefully it helps you :D
-The main concept of the game and the story around it is pretty interesting.-Visually the game has some moments that make it shine by giving the player some really awesome views of the depths of the sea.
-Good gameplay mechanics and very well implemented with the use of different kinds of cameras.
-Level design is well done, I got lost one or two times, but I'll say that it helps the player to get into the game as you can get lost but not too much thanks to some of the gameplay mechanics.
-I would add a more visual health system for the vehicle as when I died after hitting the walls various time there wasn't any clear indicator of the damage I was dealing to it.
-I don't know why, but near the end of the game the dialogues stoped having audio.
Hopefully this is useful to you :D, also if you could subscribe that would help me a lot :)
