Thanks for playing, fog density changes because, I and my playtesters think that game was to easy so I added this little challenge, the ships haw to spawn every 61 seconds and at the start, so I don't haw any ideas why ships wasn't spawning in time, for sensitivity I'm thinking to add settings in next version, lookout platform is just for decoration because I forgot to make model which size would work whit trees. Sorry for bad experiences and bad grammar.
