Make the game a steam game and add alot of all those features that is sais in the comments :) I think people will download it alot and will love playing it like minecraft :)
I really think this game is good but there is something that I would love. maybe its too big a change I don't know but I think it would be cool if it was a deserted island where all the things are with note, letter etc.
I really love the car princip :) makes it a lot easier :) But I think it would be cool if you made it so you have to get/make gas for the car so it works:)
Maybe even make et possiple for the player to build a camp to survive:)
Just some ideas I got :9 hope you will use them or at least see them ;)
