pretty much this update has very VERY little content, there were 3 new areas added and two new characters added in 3.0, along with these characters are like 2 scenes a piece and a couple of other random characters got 1 or two new scenes, there appears to be more going on in the way of a story but literally its like 3 sentences, 0.3.5 seems to be where everything we expected to be added will start, and yeah 0.3.0 is a buggy piece of work, nothing game breaking just alot of wear text pop and out of place text, overall i would suggest everyone wait till 0.3.5 because 0.3.0 is milked to hell, if i were one of his patreons id be pissed.
EDIT: while there are 3 new characters in 0.3.0 i dont count the girl from lazy town because she doesn't do anything at all, you cant even really talk to her, she just stand there.
