Once I wrapped my head around the alchemical symbols and sequences (took me a while to realize that tiles don't have to be adjacent for matching, and that you do have to go through the quicksilver-to-metal matches in the metal sequence, so first matching quicksilver and lead, then quicksilver and uh whatever the next one in the diagram is, etc), Sigmar's Garden actually became rather easy: just let the lead-to-gold sequence guide your direction of attack, and remember that if you make one salt match with an element, you'll have to make a second one as well later, so you don't end up with just one of that element that then can't match anything.
Even though it's easy, it's fun and pretty, and I seemed to want to keep clicking those little round tiles.
(I adjusted the volume levels of the music and some of the SFX that were too loud; they're .ogg files so I just used Audacity's Amplify effect to tone them down a bit.)
The game never actually tells you the English names of the elements and all of the metals. But I guess as far as the elements go, red is Fire, light blue is Air, aqua is Water, and green is Earth.
