It was a long time since I played it, and I forgot the name, but I hope someone can help me:
It starts out with some kid in a village, and some evil force wipes out all of it except him and the village head's house. You have to go in a nearby dungeon, fighting monsters with a sword, and recover orbs which are actually pieces of the village. Midway through the dungeon, you find some girl with cat ears in an orb who has a slingshot and joins your party. I only got to the end of the first dungeon, where you had to fight this dragon thing.
This is most of what I remember, hopefully someone can work of this and help me.
