This is fun. The water texture tweaks my weary old eyes out though. Thought I was going to start hallucinating there for a second. Really not sure how I got to the sea king on my first try. On try 20 and can't get to him now. Anyway, nice work!
Thanks for the motivating feedback! First try is a little easier because we have 100% chance for standard cannon to be dropped. After buying stuff it is random if you get a new gun or only upgrade.
