I think you guys should change your graphic instantly, even that bustabit type of graphic that keeps on going up is better because it at least shows how high it is going.

Yours is like at half when its x2.5 and than its only slightly more when its x5 so its graphically not correct at all and what are you going to do if it ever reaches like x100 one day? That is why I think that graphic is not helping you out at all and looks very amateur and not ready at all, you should switch that to something else right away, the problem is not the x2.5 or something because if you make that x5 or not that doesn't matter since this technically has no end going up so there can never be half of something that is endless. I think the style of the graphic should completely change to something else.
