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.
YMMV: Family Guy Back To The Multiverse
Anti-Climax Boss: Long John Peter. His level can be very annoying to some players, especially due to the wave upon wave of pirates you have to fight on a single health bar. Long John Peter himself, however, just has a few rather predictable patterns and is pretty easily beaten.
Goddamn Bats: The large wheelchair enemies with tasers in the handicap universe level can ram you, which stuns you for several seconds and leaves you open for attacks by other enemies. They often do this from offscreen when you aren't paying attention to them, or several may do this to you in sequence. This is especially annoying during the Crippletron boss fight. If there are three or more of them, you have to be especially careful because they can trap you in corners and completely drain your health in seconds with their tasers.
That One Boss: Evil Stewie. His tank is pretty much a Damage Sponge and the blasts from the cannon can do immense damage depending on how he hits you. To make matters worse, Evil Mayor West flies around on a jetpack throwing bombs at you (which take away about a quarter of your health) during the fight.
