This gives me the same feeling as finding my opponent's ship in battleship, I love how you managed to incorporate that into a singleplayer game.
I think it'd be a lot cooler if we had a way to search for things in the overworld itself, alternating between keyboard and mouse controls feels very clunky, almost like I'm alternating between two different games. I'm also not sure what's up with the custom cursor, it makes things a little harder to play, at least in my opinion.
