Thank you for the nice comment! I'm glad you had fun.
About the glitch, maybe you didn't move far enough from the starting area? Ships don't respawn from an area (which is... a bad choice from my part, but lack of time, you know ^^'), you need to explore the map more I think in order for the game to generate new islands with new ships. I mean, I hope that was it.
Thank you for the AI comment too, I did spend time coding it and I'm still losing hair over it! Haha :o
I actually forgot to enable some AI ships that hunt you down (they'll be in my next update)
Thanks for spending some of your time in my game :3
