Can't pass level 23!!

[Zithorio]

I don't know why but even bosses don't give me exp anymore! I got to level 23 in balefort castle and suddenly I couldn't go further! Did I do something wrong or maybe it's a bug?

Too bad I don't have the money required to sponsor this game sooooo muuuuch, 4$ and I can't pass lvl23. I think I'm gonna quit for a while, wait for some updates, this is ludicrous! I already paid for some levels! Why can't the bosses at least give me some xp?!
