recomending game: sword and souls

I've been thinking and I wanted to recommend you a game, which can be able found online without downloading it, and one of the ones of the best I found, is this: sword and souls.

In this game we are a gladiator that have to win 30 combats in the fighting arena, for this we need to upgrade the combat skills, and equip better the character (training with one scarecrow)

Its look simple, but they have a lot of hours of play, and very hiddent secrets.
