WOW, thats a pretty big score:) It really shows how bad I am at managing difficulty... A friend told me it was really hard, another one it was really easy, so I just let it like this:)
That's why you increase the difficulty over time :p
I'm guessing there's a mechanic where the player gets time back for each tile they clicked, you could decrease that amount
Yes, that's definitly a thing I should've done :)
