I'll be quite frank with you: I'm tired of puzzle games. Why don't developers think of something else other than puzzles; the genre that seems to be the least successful on the App Store. Yes, Bejeweled 2 is one of the best selling iPhone games to date, but the only reason being its popularity on tons and tons of other platforms.
Now with all that out of the way, puzzle games can just suck it. But there are a few exceptions; Chromixa being one of them. I'm a sucker for eye candy or immersive soundtracks, and while it doesn't quite have that soundtrack to back it up, the looks are what will pull you in. The puzzle itself is also quite intriguing; very well thought out and different from the rest. While I'm tired of puzzle games, one more won't hurt right?
