hmmm....
I'll start with the pros. The graphics are great. I was impressed since it was a DS game, and there didn't seem to be any huge glitches or lag in the design. The level designs themselves are also very creative, and there are many cool environments. Zal's powers are pretty fun to use, especially as you get more throughout the game. The prince's abilities, such as wall running/jumping, swinging, and claw slide are cool, too.
Now for the cons. The entire game is controlled with the stylus. This doesn't seem bad at first, but it gets frustrating trying to do all sorts of motions with your hand. The only action that isn't is using Zal's powers, which you hold a button and then use the stylus. Which then brings me to this. A few of Zal's powers have small glitches. For example: Zal gets an ability to grab an orb an slingshot the prince to it. It literally took me 5 tries to get this, since I had to tap the orb a million times to get it to work.
Overall, this game wasn't that bad, but it could've been better.
