The only breaking change for me has been the update 0.30.
Before (and after) I never had to start from the beginning. I'm playing this game for a pretty long time now... :)
I like where this is heading. Love the artwork of the rat and goblin. Would love a dominant goblin, too. :)
The inventory system and fight UI could use some work, e.g. showing the stats of the items before you equip them and more clearly show the results of your attacks. Otherwise the player needs to scan the scrolling text for the effects.
