That link to that website in the corner exited my game with the final boss when he was near four times by now (my browser opens links in the same tab, instead of a new one). Great game (5/5), but I voted 2/5 because of shit like that. If I want to go to your site, I'll click by myself wherever you put a link in the menu. You don't need to put that link in the middle of the click area while you play.
For all of you that is complaining about elevators. Build them in groups of 5 floors and you get costumers happy! They find the path for their floor. Vote positive to keep this up.
