A long grind, nothing really comes of it.
It's a fun game, but only because i can't get enough of upgrading, anyone with any meagre amount of RPG experience will grind on training fights before even bothering with the "next fight" option, and as such i found the game to be a simple grind, which the autoattack made considerably easier. It's a fun game however, and simple enough, but i don't think it deserves front page.
