So I don't quite know how I didn't get around to posting this, given what a huge fan of Puzzle Quest: Galactrix that I am, but a free PC demo of the game went live late last week. You can only hit level 5, but the missions that are available until the demo shuts you down give you a good taste of the revised item crafting mechanic, the new in-game economy, and crafting.
A pretty major thought I left the Puzzle Quest PC demo with is "How the heck are they going to fit all this on a DS screen?" Galactrix PC is loaded down with all sorts of tooltips and widgets and busy high-res art. Perhaps to answer that question, today D3 Publisher released a new gameplay video that shows the DS version of the game in motion. The playfield moving around on the bottom would be hard to get used to, but the simpler, cleaner galaxy map is definitely an improvement.
So watch, play, and prepare for a few new rounds of Puzzle Quest: Galactrix addiction when the game comes out in March.
