Oh man! I've been watching your progress on the screenshot thread and I love how this turned out.
After your first post, I was like: "I really hope it plays like Uncharted Waters."
That indeed is the case, very nice execution.
I had an issue the first time the game loaded; nothing really spawned. After a reload, it looks like everything worked.
Maybe something is crashing if there isn't a save file yet? I hope you crush your bugs and expand this idea.
