Yow,
Lil' Arena suffered a web-based attack last week, through its website. As a result, all of its domains (including game-related content) were taken down by my host, to reduce further damage.
Though I haven't repaired our website yet, I have fully restored everything the game needed to function, so you can now play once again.
I guess you live, you learn - never put website and game-related content on the same hosting account ^_^
Will keep you posted on the next patch's progress via discord!
Yours,
Tall Guy
