if u are experiencing technical issues you can just go to the website,make an account and download the game (its approximatly 3mb) u dont even hav to worry abt being in a different server bcos the server is the same but if ur using two accts in the same computer, they wud share energy....
Actually Akaneiro is headed to steam very soon, so your dreams shall be answered :)
