Great game. I loved being able to crash a ship into another ship, that was very fun.
However, I occasionally noticed these white vertical lines for a split second in the waters when moving.
I was wondering for the background did you copy-paste a bunch of those images? I had a similar issue in another game. I fixed it by changing the draw mode in the sprite renderer of the background image and then increasing the size. Sorry if I'm wrong or overstepping my bounds about this.
Still. great game and keep up the good work!
