Thanks! Did you play the broken version or the full version? The version posted in the comments section has fixed sound, cutscenes, full narration, and the concert minigame.
The hit box on the maid cafe one is actually the speech bubbles, so as long as you overlap them it should work. In hindsight it was kind of a bad idea.
The different clothes in the dress up minigame just change the audience reactions a bit with the exception of the t-shirt which gives you extra points.
