For $6.00 on sale, yeah, definitely worth it. However, the ending left me feeling as though the devs just wanted to wrap it up or maybe leave an introduction to Blades Of Time 2...probably the latter.
The graphics, for its time, are very decent. The story is also decent and the gameplay is challenging but very acceptable. Other than the chick, Ayumi, talking excessively and pointless, the game is actually fun to play. The "skill tree" is interesting but loot is kind of dismal.
The thing which ruins it for me is the ending. You fight for so long, killing all the ending bosses (very challenging), only to have a few seconds of a cliffhanger for, I reckon, BOT 2. It's like the devs were like "Well, lets end this in a hurry", regardless of whether they wanted to leave an opening for BOT 2.
I may play this game again in the future, but, honestly, I'd have to be pretty bored. As for now, I don't see Blades Of Time having much replay value right now. And the DLC that comes with it, I just quit out of boredom.
So yeah, 3 out of 4 stars for me.
