- Anvilicious: Typically the major criticism of the game's plot: between the opening dedication, Quico's flashbacks, the statues, and the entire "final boss" fight, it's more than obvious what Monster is supposed to represent. That said, this may have been intentional on the creator's part:"Why did we need to see whiskey bottles turned into frogs? Wasn't it obvious that's what was going on? Caballero pointed out Papo & Yo takes place in the mind of a child, and a child who is the victim of abuse rarely sees his abuser's actions as such. They can't see the truth. Sometimes things need to be shown explicitly before healing can begin.
- Fridge Brilliance: At first, it's funny to see Quico getting rid of frogs by splatting them against the wall - but when The Reveal hits that those frogs represent bottles of liquor, why this works becomes crystal clear.
- Fridge Horror: When an enraged Monster catches you, he throws you around, but you recover. However, when he catches Alejandra, Monster turns his back to you and then she's gone forever. Then on the final level, there are actually at least a dozen Alejandras that he can consume, unless you engineer an escape for them. What did he do to all these girls?
- The implication seems to be that the girl was Quico's sister in reality, and was likely either killed by their father's abuse, or at least taken away, depending on whether Child Services exists In-Universe, and the only reason that Quico needs to repeat the process is to hammer the point home.
- Polished Port: The PC version, released in April 2013, was a huge improvement over the original. It had practically every audio/video option you could want out of a PC game, as well as sharpened graphics, the ironing out of many Game Breaking Bugs (some were left in, but they bordered on Unintentionally Unwinnable), a silky-smooth framerate and excellent keyboard & mouse controls as well as supporting an Xbox 360 gamepad.
- Tear Jerker: Arguably the entire game considering the fact itís about the creator's real alcoholic abusive father.
YMMV / Papo & Yo
