The virtual pad is too old. Flick is old too. The latest is the point-appointing movement along free curves which I invented. On touch devices, the easiest controlling action RPG is born. Control Nacchan to eradicate pests. You only need to touch on your screen. You attack automatically. In solo mode, eradicate pests in the cave. In two play mode, Nacchan battles against Siichan. With this incredible UI, enjoy this all new action RPG.

Pitter Patter RPG's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
