If there's anything to be learned from sci-fi-drenched tales of time travel, it's that fiddling around with the past and altering key historic events almost always has unintended--and potentially catastrophic--consequences. It's a hallmark of the classic Back to the Future films, and a plot mechanic that's getting a lot of clever play in Telltale's new episodic adventure gaming spin-off of the series. The debut episode set the right tone with a strong story and engaging characters, making up for its gentle puzzles and limited scope. Things get rolling more steadily in Episode II: Get Tannen with its snappier pace, entertaining character developments, and some minor but meaningful tweaks to the formula.
Get Tannen plays out across some of the same settings explored in the previous episode, though you also visit a couple of new spots that offer some welcome changes of scenery, like a seedy nightclub that transforms into an "ice-cream parlor" at a moment's notice. Changes in perspective and different camera angles minimize the feeling of deja vu when you're returning to familiar areas like Hill Valley's park and downtown. Beyond making old scenes feel fresh, the way the camera works this time around is a definite improvement. There are still moments when sudden changes in the camera angle during transitions from one area to the next make adjusting your direction in mid-walk a little awkward, but many sections switch things up with dynamic views that shift as you go. Some puzzles feature a static first-person perspective that lets you pan around a scene a full 360 degrees to interact with your surroundings. There are even a few spots where the camera offers a more traditional third-person perspective and moves closely behind Marty as he meanders. This constant shifting blends well with the new areas to explore and keeps the episode from dragging. You never have to stay in one spot for too long, and the time it takes to hike between areas is minimized.
Back to The Future's puzzles are still a cakewalk compared to those in other similar episodic adventure games like Sam & Max, Tales of Monkey Island, and Wallace & Gromit. That said, the puzzles are exceedingly clever and fun to play around with, even if they're a little on the obvious side. Get Tannen features a handful of the standard "use item X on hotspot Y" adventure game puzzles to bridge the gap between dialogue-based challenges and more elaborate conundrums. Some of the episode's more entertaining puzzles include creative challenges that have you fiddling with sheet music to influence important characters, jockeying for position among a gang of ill-dressed ruffians seeking to cave your face in, and using your surroundings to pick off mobsters without being caught. Overcoming these obstacles isn't very hard--the game's multitiered hint system is rarely needed--but they fit so well into the context of the situations you find yourself thrust in that the lack of a real challenge is forgivable.
