Advice/info lines

[TylerBence]

Hello,
for some reason, my game doesn't seem to display onscreen lines that are supposed to provide you with information about a given object. I'm talking of aiding lines that are displayed along with the eye icon (ex. you're pointing at a lever and you're supposed to get "electricity has to be activated for it to work", without clicking on the abovementioned object), instead I get nothing, so I can't really figure how to get past levels without watching gameplays in order to know how to interact with the surroundings. Basically, it's impossible to play like that. Can anyone please help me?
Thanks forward
