This game is good. But good is not your style. If I understand correctly, please correct me if I am wrong, but the purpose of this game is to be a multiplayer game Diablo style, correct? Well if you are aiming for something like that you cannot be so, for lack of a better word, narrow. You are making areas very small and are creating the game so that you basically guide the player to certain places. What I'm trying to say is that areas in the game are too small. I often find myself running for two seconds and already hitting the barrier. Games like Shadowreign RPG and Arcuz have vast environments that you don't bored of.
Which brings me to my next issue. There is no color but red! I know this is your style but when it comes to games like this, you need to catch your players eye to keep them going. It really puts a damper on things because half of the fun in games like this is running around and exploring which, if the environments are bland and small, you have no fun doing it!
Aside from that there are only minor issues. Lack of weapon variation, lack of enemy variation, lack of enemies thereof, music isn't very enjoyable and lack of customization in any way, shape, or form. I eventually became bored of this title rather quickly and thus gave it only a three. All in all, this is a solid game but from you I'm not looking for mediocrity. Although, if you addressed these issues the game would be much better.
