Chronosgear is yet another match 3 game. It is different from games like Puzzle Quest, however, since you stack colored units with varying degrees of strength and health. Vertical matches provide offensive attacks while horizontal matches form walls for defense.
The game is fine enough for $1.99, but there are some issues. First, balance is a major problem as bosses jump as much as 40hp from one mission right to the next. Moreover, the game world is not very interesting at all.Further, the writing is terrible.
Maybe the biggest gripe with the game is that it is a straight copy of the Nintendo DS game, Might and Magic: Clash of Heroes. That game is quite good and of very high quality. However, even at its current price it is more expensive. Chronosgear is a good value for the money, and if you do not own a DS, then this game might be worth your time. However, if you do - spend the extra money and get the real deal - its worth it.
