Amateur Surgeon/YMMV


 * Surprisingly Improved Sequel: The first game and the Christmas edition were very well-received, but the sequel removed every single Scrappy Mechanic and streamlined the controls to make for an even better experience.
 * That One Boss: The 2nd Dr. Bleed surgery. All the various hard-as-hell surgeries (which are usually made hard by Guide Dang It moments,) tend to be much easier once you know the trick behind them. The 2nd Dr. Bleed surgery, on the other hand, is a four-part Marathon Level against poison, fire, buried chunks of crystal, and finally a tapeworm that takes more hits from the battery to kill than the last tapeworm (and can quickly cause Bleed to...er...bleed out if you're not multitasking between cauterizing the cuts it makes and zapping it.) And you have just enough time to do it all quickly and flawlessly.
 * Napoleon Trotterski from the second game. It starts off easy enough, but suddenly ends with the player having to spell out words on a Speak 'N Spell. And if you aren't fast enough, the Speak 'N Spell suddenly explodes, leaving flames and burn marks that'll almost certainly obscure the screen and the keys, and if you try to put out the fire/heal the burn marks directly when they're on the keyboard, the game will assume you're hitting the keyboard instead and explode a second time. Not that you'll have any time to put out the fire anyway, because the words are coming faster and faster while you're trying to spell them out while not being able to see what the hell you're supposed to be spelling because the goddamn fire is in the way.
