I am sorry to hear that the game crashed! Can you describe how/when that happened?
Glad you liked it non the less :)
[Potential Spoiler ahead]
Currently, there is no combat in game. As some of the instructor's lines suggest, I originally considered adding pirates to attack after the tutorial. Would be a nice prelude for a bigger game :D
The further development went, the more it felt like this should be a relaxed, peaceful experience. So I ditched the idea. Wouldn't have had the time to implement combat AI anyways...
