Yo, I played Soldat too.
A flash version of Soldat, I can dig the idea. Your picture might be a tad too similar to the one on the Soldat homepage.
On a technical level, dual weapons have issues reloading. The far hand never has to reload, making dual weapons far more powerful than they may have been intended. Also, when using the knife, the stabbing arm turns red. Seemed odd, since it was clearly not from blood effect, but just turning red.
A bit slow gameplay. Could use a bit more speed to keep it interesting and lend more use to the knife. As it is, the knife is unplayable almost due it taking so long to charge an opponent. And as everyone has unlimited reloads, there is little reason to ever use it. A fun idea, but pointless in practice as it stands.
Over all, it is a bit uninspired, and does not carry over the fun of similar games.
