I like the game the art is very nice. It makes fun. if i can change something i would change the rotation from the player i would flip the image becouse the rotation is for a 3d game and not for a 2d game it looks unnatural.
Thank you for the long Feedback. It is intentional that you can only control one thing (player and submarine not at the same time). I'm always happy when people like my game. I hope you don't notice that I actually speak German😅
