Okay, this is not meant to offend you or downgrade you in anyway, alright?
So first thing is first, this is FAR from "alpha" testing. If you look at other games when they're in alpha, they are not this underdeveloped. The webpage isn't even finished yet and the server is very glitchy. If you want, I could help you develop the webpage and translate some things. The messages and text is very hard to understand; it has very poor grammar.
Another thing is that a majority of users on this forum speaks English and/or German, so recommend making a multi-language function so people can switch from English, German, or Spanish.
Other than that, I would like to recommend you taking it down and working it to the point where the webpage is AT LEAST finished. The server might also need a bit of work. Oh and by the way, use a VPS. Do not ever use a computer or Hamachi to run the server.
