Thanks for the input and the video! About the navigation, I've realized it's the issue after I was 7 days in the game development and all I've done to help was add the map of the island (which doesn't helps much). Roads usually lead you to something but they are not very visible and I should have done something better in hindsight. I'm planning to make new version of the game (more serious as in not just as a challenge) and I will definitely think about it more.
