Galactrix lacks the gameplay and customization depth of the two fantasy Puzzle Quests (1 and 2), but adds a hexagonal varied-gravity aspect that is a nifty, challenging change from its vertical predecessors.
I had a lot more fun customizing spells, skills, mounts, and equipment in PQ1, and equipment/skills/spells in PQ2, than I did customizing my ship in PQ:G. Once you find a good balance of skills, you'll almost never need to change your strategy. Regardless of strategy, though, the opponents seem to have preternatural luck, and many times you'll win either by reloading or just saying "♥♥♥♥ it" and trying to set off lucky chain-reaction matches. I never really felt chuffed about outwitting the game's enemies like I did in the previous two games. Oh well.
It's still fun and addictive, and the hexagonal system makes calculating chain-matches satisfyingly tricky, especially when gravity-altering skills are in play.
There's a forgettable "faction loyalty" system that you can game by selling piles of commodities in areas you want to like you.
Controlling your ship via cursor is super clumsy; good luck trying to evade enemy ships with any degree of skill, because skill isn't a factor.
Minigames are tepid compared to PQ1, consisting of a strategic match-as-many-as-you-can-before-tiles-run-out game (mining), a speed-matching game (gate unlocking), and a game where you try to avoid setting off "bombs" by conservatively avoiding chain matches (information gathering), and a crafting game where you have to match certain quotas (which I didn't play much, because crafting is almost entirely unnecessary). The gate-unlocking game is annoying, especially given how many times you'll have to do it; the other two that I played are mildly fun.
STORY: The frame story is boilerplate junk full of minor textual errors, but that's par for the Puzzle Quest course.
GRAPHICS: Pleasant, though unsophisticated. Nicer than PQ1; not quite as nice as PQ2.
SOUND: Music is pretty good and a pleasant listen. SFX are fine.
OTHER NOTES: PQ: G is surprisingly taxing on system resources for such a lo-fi game.
RECOMMENDED? YES if you liked the other Puzzle Quest games, are a fan of puzzle-match games, want a good time-waster game and haven't played the other two PQs (the Marvel one's an F2P scam and doesn't count), and/or aren't hard to please.
NO if puzzle games aren't your style, or if you're a snob for quality.
