Hi ZomM. I wrote the information on the page and yes, it is normal. The game does not have any harmful software. If it did, thousands of people would write me pretty bad things, don't you think?
Anyways, if you don't want to, don't play the game, but there are over 50 comments who has played the game and nothing happen. Note that. There is no need of "DON'T INSTALL THE GAME" quotes, alright? Thank you.
