Wallace & Gromit's Grand Adventures Episode 3: Muzzled sticks to the WASD movement scheme of the first two games in the series, and while I've gotten used to it, the switch from point-and-click to this is always a bit jarring when I load up a new
Wallace & Gromit adventure. But I'm sure a lot of that has to do with the number of point-and-clicks I play between
W&G releases (which is higher than average).
The WASD keys (or Direction keys, if you want) are used to move Wallace or Gromit around in the 3D world. The Shift key brings up your inventory, and your mouse-hand is left clicking only on inventory items or items in the world to interact with. Like I said, this doesn't take long to get used to. It's different than most adventure titles, but for some reason, it works for Wallace & Gromit, but it doesn't feel right in other games (like the recently released Casebook: Episode II: The Watcher).
Put simply, if you've already been following the Wallace & Gromit's Grand Adventures series, then you won't be disappointed in this one. If on the other hand, you haven't played any of the games yet, then you should definitely give the series a try (provided you are a fan of either adventure games or these two characters). While the games are very episodic and don't require knowledge of the previous adventures to know what is going on (which might change in the next game considering how this one ends), it's still best to start this series from the first game two episodes back, just so you can revel in all the goodness that is Wallace & Gromit's Grand Adventures.
