It's different I'll give you that, I also like the fact it's not just another Mafia game.
Not too sure about the landing page once logged in (selection.php) but I'm guess this is for when you get more games within your network.
I don't really like the layout however it's better than some I've seen recently, also there is too much going on.
Upon first login into the game I have a chat at one side and a user in chat at the other side, which in my opinion should be at the players discretion to have open or not.
Like A_betrand said, there is no story for when you first start which means to me until I reach level 10 as you said I'm stuck clicking and nothing else.
Training isn't really user friendly I have to type the amounts I wish to train, so I'd suggest having pick-able options, then maybe an 'other' selection if what we want to train isn't there in the predetermined selections.
All in all you have a nice game it just needs a little work.
