The more noticeable shake-up to the
Puzzle Quest formula is the game board, which resembles the XBLA game
Hexic more than
Bejeweled. Although the board may look different, it still uses the same core, match-three-or-more gameplay. The biggest change comes from how blocks are replaced. Rather than dropping from top to bottom, blocks will also come in from the sides or bottom depending on how you match them. It's confusing at first and though you'll eventually get a feel for how the fall patterns work, it never feels completely comfortable. Chance has always had it's place in the series, but with the new system, it can sometimes feel like a little too much is given to chance, which helps to create a "cheap" feel when taking on the computer.
Clearing like-colored blocks still rewards you with colored energy for attacks but Puzzle Quest Galactrix alters things just a bit. Rather than choosing a specific class, attacks are based on how you outfit your ship. Early on, you are limited to a handful of parts, but as you travel the universe, you'll uncover new weapons. Additionally, a new type of special block joins the damage-inflicting ones. Matching blue blocks generates shield points that will protect you from some attacks.
The addition of shields adds a completely new dynamic to the flow of play. In Puzzle Quest, players would usually gun for matching up skulls, which cause direct damage. Now that shields are in play, there's a really cool "Attack or Defend?" decision-making mechanic at play.
While I don't see myself buying as many versions of Puzzle Quest: Galactrix as I did the original Puzzle Quest, it is still a worthy follow-up and worth playing.
