These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
How about the vocal songs? I mean they sound pretty good, the ending song to the first game simply titled The End that plays after you beat the game is really good, and the sequel brings us Light of My Life and the other vocal ending song Real Life.
Ensemble Darkhorse: Let's face it. The majority of the players love Crazy Barks. It's probably one of the main reasons he was such an important character in the sequel.
He even gets an expy in the second town of the game. Crazy Diggs. He looks exactly like Barks, but is gray and wears a suit instead.
Fridge Brilliance: Regarding the Dream Apocalypse. Because the Raposa are rooted in Mike's imagination, it's impossible to destroy them outright. The most he could do is put them aside for a while to wake and live in Real Life. But dreams are by nature recurrent (that's just science!). The next time he sleeps and dreams, the Raposa are free to return as Mike imagines them. Sure, this makes Mike God and the Devil to them, but that's not a foreign concept to the game.
In addition, leaving Mike in a coma to die would not have done the Raposa any favors. As products of his mind, they are a part of him. With Mike dead, they're dead too.
Heather's last words before being kidnapped at the start of the second DS game, "Kemi-kewa, kemi-kewa". Astute players may realize there is a meaning. "Wake Mike! Wake Mike!"
Nightmare Fuel: The ending of the DS version of The Next Chapter. Once you make the connection to the beginning, you find out that the Raposa are ending their own world, and watched the end credits, nevermind that it was All Just a Dream.
Viewer Gender Confusion: Seeing how you draw your own character, you can choose to make them male or female(or otherwise). However, there's no way to actually set the gender, and your character will be referred to as "he" and "him" various places in the game even if they're a girl.
