Start moving west and think like a paramecium: turn right at every intersection excluding the start, and counting the destructive obstacles as walls, until all the chips are collected. This route will end in the socket area, which is no longer a barrier, allowing for quick passage back to the exit. The bold time is 229.0 and thus requires exact movement, but little else.
Trivia
One level by Eric Schmidt includes much of this level's original maze, but with more bombs and no other destructive obstacles, and with the teeth and walkers left free to wander the level. Entitled AUGHHHHHhhhhh..., it can easily provoke such a reaction, usually when a walker lodges itself inside corridors; if one gets between the chips at [3, 27] and [7, 29], it will stay there permanently and, as there is no place to hide, safely collecting these two chips requires luck.
