Well, I have beat all of your available missions, I absolutely loved it!
A few things I noticed..
Knights who are freed from cage make the sound of a mecha knight when hit, and can be separated from your party if a gate closes (no button teleport abilities) As well as this, they don't seem to die, I made one stand near a gold drone for a while and he just couldn't go kerpoot.
BROKEN: The first prestige mission of freeing the knights from the devlite prison, completely broken, I played through all the way to haven, it refuses to start up, always giving a error.
First reaction to the 'toy soldiers' mission was "Wtf is this thing, it has the shield I want."
Great remakes on all the haven NPCs
