The characters are overdesigned, poorly written, and amateurly voiced, making them utterly unsympathetic. They talk and behave like a bad parody of sunday morning cartoon characters. It was baffling to see that after going through 8 content warnings on the game starts. Is this supposed to be for kids? Is it not? Characters behave like it is, but the content warnings suggest it isn't.
Either way, I dropped the demo half an hour in, because I caught myself thinking I want something bad to happen to all these people - anything that'd make them shut up and stop being a bunch of annoying morons. And that is definitely not the mindset I want to have while playing games.
Still, I appreciate the fact there IS a demo at all and I had a chance to figure out I didn't like the game before buying it and wasting everyone's time with a refund, so no hard feelings.
