I just got through the Old Haven Castle.
It was great, it seems like you must have put a lot of work into this.

Just a couple of minor bugs I on my end. (No biggies really.)
At 100% TP Garret's Radiant Blade skill wouldn't trigger, nor would one of Pengin's,  Valiant Edge I think.
Also two chests that would not open, one in a coffin room at the prison level and one upstairs from that level.

For starting out semi annoying, (The low hit rate on the Rats ie. ) this game is  good. Very good!
I am off to see the King I guess.
