With a slightly different twist on the typical puzzle game, Gyromancer could have been a little better, but was still fairly satisfying.
The gameplay is about what you would expect of another 'Puzzle Quest' type game, just with a few different rules concerning the switching of gems. If you liked 'Puzzle Quest' then you'll probably like this one too. The story was actually interesting, but was unfortunately very short, could have been flushed out better, and at a few points left me a bit confused due to seemingly random plot points.
That having been said, Gyromancer's one true failing is that it is far too short. You'll likely only get about 10 to 15 hours out of story mode assuming you poke around a bit. Despite that, if you're in the mood for a decent puzzle game, or if it's on sale and you'd like to have something to pass the time other than Solitaire, then by all means buy Gyromancer!
