Is she using a Famicom controller (or reasonable facsimile thereof)?
Playing Touhou with one of those would be incredibly difficult, because you only got 2 buttons. You need at least 3; one for Bombing, one for Shooting, one for Focus. You need a 4th if you want to pause, and in the older games, a 5th if you want to skip the cutscenes.
Sure you could bind Bomb to Select, but then you'd have to take your hand off the D-pad to bomb, which can kill you.
\Pichuuuun!!/The sound of dying in Touhou.This is hard...
