In short: It's a fun little game. Definitely one of the better ones on my list.
By no means is it perfect, but it has plenty of charms going for it.
Good:
I liked how fluid and easy the combat system is. Punches, kicks, slices, bashes, and magic bolts all flow into each other well in what is, essentially, a free form combo system. Smack enemies around however you want using an array of acquired skills and special moves; primarily with the goal of locking enemies into painful juggle combos and smashing them into the hordes for group damage. It is quite satisfying to high kick an enemy into the air, use a Ether Saber uppercut, and then Reverse Spin kick them backwards into the row of enemies behind you.
There are also some rpg aspects there; but it's not really developed. You get experience and 'level up' but it's not all that noticable. You do however get to buy upgrades and equip new special skills and passive skills to change your style and tweak your game. A fair variety of magic attacks, melee skills, and useful passives lets you come up with quite a few interesitng combinations, and with the free form combo system included it's hard to imagine the sheer number of attack patterns and strategies at your disposal.
It's a good challenge too! Surprisngly difficult and unforgiving at times for such a cute theme. Bosses have a whole repertoire of special moves that they can play on random, and are quite capable of keeping up with the agile little fairy brawler. Hordes of faceless mobs will pummel you to the ground, shoot you mercilessly, and all together are quite capable of overwhelming the heroine and knocking her out in seconds. It's a game you have to stay on your toes with.
The music is also good and plays well to the different settings. There is also some japanese voice acting, so that's cool I guess?
And the game is cute. Freesia's a sweetheart to be sure. But if you aren't into anime stuff then there's not much story or lore going on anyways. Cutscenes are pretty barebones with still graphics and text that are overall pretty short, with in game animated scenes lasting only a second or two. Everything else is pretty much left up to the player's imagination. Characters are kind of interesting in personality and design, but you really don't see enough of them to make it count. It's overall standard anime/fantasy story stuff, and that works for me.
Bad:
The game is painfully short. Can be beaten in under an hour if you're fast. Maybe two or three hours on the higher difficulties where you'll be taking your time. For such a sweet and well developed game, it ends quickly and becomes repetitive soon after; albiet still quite amusing.
Repetitiveness is the main problem here. It's not terrible, but defintely the weakest point in this game. There are only five main arenas to fight on, and only four enemy types(short, tall, flying, and giant). Some enemies develop into sub-species with alternate attacks, but for most of the game you'll be facing hordes of the same four faceless enemies again and again. It doesn't help that the first boss is just a bulked up version of a regular enemy as well (thankfully the remaining human boss fights are much more diverse).
There is also a sort of endless quest mode, called 'Guardian Mode', that has you try to fight for 99 levels of randomly selected waves, but that's even more repetitive. Sometimes I ended up clearing a level only to fight the exact same lvel setup right after; there's not even much variety in the randomized stages!
It is a little slow in the beginning too, when you don't have any basic skills upgraded (and with the first boss not really being that hard), you're stuck using the same moves over and over, and it's easy to get a bad first impression for the game. Things don't start getting interesting until the second arena, but with the game being as short as it is that is a huge minus.
But with the lack of diversity in the challenges aside, it's still a pretty fun game.
Overall: I would have liked a little more variety and challenge, and maybe even a little more story as this game is quite charming despite being relatively simple. The rpg mechanics could have been a bit more interesting too, but I won't exactly criticize that.
It's a simple beat-em-up about a cute fairy trying to save her tree that features a pretty awesome free form combo system that lets you smash around enemies and tear apart hordes of faceless golems in whatever fashion you want. Despite it's cute theme and repetitive challenges, it is quite difficult and quite fun to play. A "can pick up and finish in an hour" short, but still good fun while it lasts. There are multiple difficulties, plenty of skills to master and try out, a new game+ mode, and an endless mode too if you want a little extra fairy fighting action.
It's just plain fun, and cute as a button to boot. I recommend it, especially for the low price. If you like beat 'em ups then there's no reason not to give this one a swing.
