UPDATE I NOW REMEMBER IT'S TOP LOOK (YOU LOOK ON THE CHARECTER FROM ABOVE)

Details about the game:
I think the game was released between the years 1995-2000
He is a game that gives 4 / 3 options of players.
Two-dimensional game, he was not Online

1. Warrior
2. Keshet
3. Mage
4. Can not remember if it was

There were also key: bronze, silver and gold.
There were bosses (for example, was small spider I would sometimes get a giant spider boss)

It's a game if the quality is not anything.
I remember at the beginning of the game would have to kill spiders.
Such was the keys that need to take to continue.

* This is not one of these games **
(Mu, Maple Story, Gauntlet, 9dragonos, travia online, Heroes of Might and Magic, Dofus, Forsaken world, lineage 2, wow isreel)
