It doesn't.
So anyone familiar with the rubbing on Monster Monpiece? I try to level up a card, but I can't even get the tension gauge to a quarter of it. I just found out that you can pan the camera with the L or R stick. The tutorial didn't mention this at all. Does touching the rear touch pad do anything? I only have a minute for each rub and it seems super gimmicky to power up your cards.
1) Tap, don't rub. Move around the image tapping until you see hearts or stars (which doesn't matter), then mash taps on that location. Common locations are chest, hips, shoulders, but it can be almost anything. I've seen it be wings and tails before, but not random space outside the character. Once it stops making hearts/stars, stop and move on
2) There are 2-3 points you need to complete to fill the guage. Better/more expensive cards are much more likely to require 3 points
3) The double sided rub, best I can tell, is totally random. If it's too humiliating (or you're on PSTV) you can just ignore it, it's free tension points but never necessary to win
4) There are "pinches" and weird crap you can do, but best I can tell the best way is to simply tap all over, never pinch or rub
5) It's totally possible, but a bit hard, to win the game on PS TV. Same strategy on Vita. Even the double sided rub is possible by clicking both sticks, but it's awkward. ...more awkward
