So, as promised, Irene, here I am.
I've found that this game has the strange problem of getting almost easier as you progress in the game, especially if you choose your elements correctly. I tend to start off by getting up to 25 Water Elements for Healing 2, and then for 36 elements to get to Magic Barrier. Nevermind this also gives you access to Avalanche, which is the single best attacking spell in the game and is a godsend against the final boss, who likes to take three and four hits of 70 damage apiece from it. Discounting the all of 5 or 6 enemies in the game that have a physical attack, this makes you borderline indestructible. I find that while wind gives some nice buffs with Wind Walk and the Constriction spell (I think that's the one that binds enemies), Fire is better for Vampire's Touch, since, as everyone knows, the staff damage is just obscene, and recovering 50+ HP while doing so is better still.
Now, don't get me wrong - I like the game, simple though it may be. It's a bit on the easy side if you optimize and/or grind, but then again, what game isn't? I don't think the game would be easy at all if you started by taking wind as your starting element, although it certainly would make the first boss pretty easy if you spam Wind Cutter III at him from a distance and have learned how to dodge his beam spam attack. I'm not sure how hard the game would be if you took Fire as your first element. You'd have Vampire's Touch and the spell that boosts your staff attack, but you'd be taking major pain from bosses like Zelse, and I'm not sure if you'd be able to outlast him when he's hitting you for 35 (when you have ~115 HP) and you deal maybe 70 at this point against his 550+ HP.
So, there's my thoughts on the game. I really should play it again at some point.
