Thank you for your comment. Yes, as I suggested in other posting, the current battle system is too boring :( Especially now due to the encoding, users cannot even know if they're being attacked unless they're logged on. But we should admit that the current version isn't that interesting to keep the login.

When the encoding was introduced, fight wasn't encoded, and I expected the official attack alarm app would be launched, but fight is now also encoded. I believe @drugwars should provide the attack alarm app.
