Anti-Climax Boss: The second and third bosses (Abominable Snow-Burns and Ramses Burns) are both way easier than the first boss, Fu Manchu Burns.
Porting Disaster: The version released for the Master System and Game Gear strips out all the storyline sequences, has even worse controls than the NES version, and strips the soundtrack down to just two short, repetitive tunes.
Scrappy Mechanic: The controls in general. They're not quite as bad as often reported in that they do work right consistently, they're just unnecessarily peculiar. Like its predecessor, the game has the same control scheme where the same button is used for running and jumping, and so to take a running jump you have to hold the attack button and hit the jump button (which in this game, causes you to waste ammo every time you take a running jump). And Bart skids after taking a long jump, making precise jumps difficultnote the trick is to turn Bart around so he's facing backwards as he lands - again, it works consistently but it takes a while to get the hang of, especially with the controls being so odd
That One Level: The Hollywood section of the game in its entirety, as the levels are far longer than in any of the previous three sections, and turn into pure Platform Hell at points.
