.. Is this game scary?

Not in the usual sense, no. There's one spot where someone suddenly jumps out at you, but after you get your breath back it's actually pretty funny. Personally, I don't mind jumping a bit if I get to laugh after.

There are a couple of ways you can die -- excuse me, make a fatal error, as the game says. But if that happens, the game gives you the option to return to the game just before things went wrong and try it again.
