ART
I adore the theme and it's homage 80s comic artwork. The back glass is an entire comic strip and features a lenticular printed panel — they were everywhere in the 80s and 90s! And come on, Dr Dude has a walkman built into his stethoscope. You can't get much cooler than that.
MUSIC
The music in this game is among the best System 11 in my opinion. When you start a game the music is geeky and awkward. Each time you attain an Element of Coolness the music changes to the theme music for that element — essentially getting cooler each time. And the jackpot music is one of my favourites in pinball — it makes you feel so great to hear it. But in an light-hearted earnest kind of way, not a badass serious kind of way like modern pinball themes.
Sound design is employed perfectly. They match what the ball is doing visually. The sounds of the magnet catching the ball, the guitar solos as the ball flies off the Heart of Rock'n'Roll target, the zaps that increase in pitch while the ball is in the mix master, flashing like mad, the ball snaking along the wireforms, exploding as it goes up the ramp. Super cool.
GAMEPLAY
I feel like it is an early version of the popular late-90s fan layout formula (MM, AFM, MB) where you shoot shots repeatedly to light the inserts and complete them to reach multiball, only these shots are three totally different kinds: magnet, standup, VUK.
The rule set is simple understand and is approachable for newbies. But getting a good score takes skill and it keeps you coming back for more. This isn't a game that you have to perform mental gymnastics to extort the rule set into giving you a great score. It's dead simple: play well; score well.
This game is great for teaching you flipper skills and honing your aiming. You're required to make all kinds of shots: backhands, on-the-fly, cradled. You learn to control the ball as it returns to the flippers. Pretty much every flipper skill can be employed to great effect in this game.
CONCLUSION
Dr Dude is one of my favourite games. It is absolutely perfect for the kind of game that it is. It's pure pinball in my opinion. It doesn't do everything but what it does do, it does right.
