Thanks for the feedback! I am glad you think the styling and music were good, as I spent a lot of time working on them!!
You're right that the game feels slow, and that's due to a lack of time to work on fov changes, effects and speed lines(all of which I will work on soon!).
I am not sure how to solve the catching up to other players issue apart from making the AI sub "dumber" by making it's racing line less optimal. It has the same speed and physics as the player sub which is why it's hard to catch up.
If you have any ideas on how I could work on these please feel free to send me any suggestions! Thanks again for playing!!
