I am struggling hard not to buy this game. Like previous commenter, I also think that the pricing model for this game is a bit extreme. Admittedly, I really dig the online highscore system; it's excellently designed and I think it plays a big role in the fun, with a game like this, but the price you have to pay, in order to participate, is... well, a bit much.
This game is radical! So radical, that I wouldn't hesitate to rank it evenly - if not before - the previous king in obsessive casual games; the Palm pilot version (not the computer ditto) of Bejeweled 2.
Whereas Frenzic has a very different plot than Bejeweled 2, its addiction-factor is just the same; you can't stop playing!
Design, look and feel of Frenzic is top notch. The sound and music fits very well in with the rest, adding a lot of immersive drama to the game. And again, the online high score system looks and operates very (!) smoothly. I like how they didn't make it just a highscore list, per-se, but actually added some further depth to it, by means of making it more 'community-like', where you can add and compare your score with friends, etc.
To sum it all up:
This game manages to carve out its own, unique little space, in a genre that is stiflingly overpopulated with tons of different casual games trying to appeal their audience. Albeit, what might throw a spanner in the works for Frenzic, is its aggressive pricing model, which, if lowered a couple of bucks, could help popularity (and sales alltogether) rise to epic propotions...!
Now, I might prove wrong just as well. (I'm not a marketing expert.) For all I know, I'm still struggling to resist the urge to splurge and buy the game, without blinking, now and here.
