For those of you wondering, to stop your insanely long combo, just go to the shop and wait. The combo should stop shortly, and you receive your cash. Then you can quit to menu, or start your combo again.
@Capinporcupine If you actually checked the first comment, iit's been flagged for review, so obviously, you can't see it, leading to him putting it in the instructions.
@Baldane & Aoi Scarlet Agreed, Touhou is amazingly hard. Was playing this game on Frantic, but thought it was around Touhou Normal level. The patterns in Touhou are beatifully mesmerizing. Frantic isn't a bad game though. Bullet dodging games are pretty fun. Frantic 2 earns a 5/5 from me.
