YMMV / Crime Fighters

• Demonic Spiders: The martial artist mooks tend to hit you as soon as you're in range, strike VERY quickly, and will knock you out of your combos easily. They're even worse in crowds where either the other enemies can keep you busy, or they can smack you in the back while you're trying to deal with everything else.
• Nintendo Hard: Where to begin? You can only hit one enemy at a time where enemies almost invariably come in groups, enemies easily slip in hits to break you out of your combos, and bosses tend to just hit you whenever the hell they feel like it and can't be stopped from doing so. Oh, and if you're playing the 4-player version, your health ticks down constantly, even if you're not playing multiplayer and thus don't have the ONLY advantage you would've otherwise had over the game's general cheapness.
• That One Boss: The Stage 7 boss, Bull, stands out in a game where just about every boss is a giant pain in the ass. His knife outranges your attacks by a good distance, he attacks faster than you, he's clearly aware of both of those facts, and if you in any way attempt to get up faster once he stabs you, he times his next attack to stab you as soon as you're on your feet again.
