Ok so what I mean by that is when you play a song with No Fail, but then in the end you would have passed it even without the mod. It would be cool if in the end there was an animation for or something where the No Fail icon gets shattered and then you get bonus score added to your total.
I dont think the exact number is that important at all, because the main point is to give that extra drive to try your best to the end when you begin to realise you can pass the song even without the mod. So maybe make it so that instead of 0,5 multiplier you get like 0,75 multiplier instead. I do not think it should go all the way to 1,0 multiplier because it would encourage to always play with NF and i dont like that for some reason. Also it would be too radical of a change and I prefer baby steps.
