Give us the possibility to return to the previous lighthouses (after reaching the last one) or an upgrade that lets us phase through the rocks. Also, make the Ghost Ship appear more (because in 120 nights, i've encountered it only one time and didn't get it, because of the rocks) and increase by 25%/30% the amount of Oil we receive, because i'm currently flooding in gold and wood (at the last lighthouse), but oil is always short.
And finally, a question: how to get the last achievement?
