for anyone who their computer is saying the file is a virus, its a game, i downloaded it and have seen no sign of a virus. the game is beautiful and functional, but its hard to tell what systems are failing and what tools you need to fix them. the holes in the wall kept telling me i needed a tool that i couldn't find and it told me to fix the cooling system, but it was literally the last sytem i checked. The first time i played i didn't even figure out where the cooling system that i needed to fix was before i failed. that being said, it was still fun and is beautifully designed, as well as very on theme.
