Help in identifying a game, GBC game

I need to find this game. It's a GBC game but I remember playing it on my GBA. It's genre is Roguelike meaning it plays like Pokemon Mystery Dungeon or Shiren the Wanderer. I think it's setting is in a small village with a really big tower full of monsters. You play as a boy who wants to go to that tower and eventually meets a blue monster that has wings. I think the monster's default name sounds a bit Japanese.
That's all I remember about the game... Mind replying if you know the title? Thanks.

sounds like Azure Dreams to me.http://www.gamefaqs.com/portable/gbcolor/data/576066.htmlI preferred the PSX version myself, but this one wasn't bad either.

Yeah, this is it. Thanks.
