This game is a somewhat nerfed version of Anubis II. Instead of 3 hearts, Trixie starts each new life with 5. She can also defeat some enemies by jumping on their heads. The hearts that appear when an enemy is defeated doesn't rise as fast as those in Anubis II, allowing them to be collected much easier. Also, Trixie's powered-up shots will actually seek out the target they're locked onto, instead of simply flying straight. As with Anubis II, you can simply use the Z button on the nunchuck controller to jump, instead of having to bother with shaking the nunchuck to jump.
The main problem is that some of the platforms and blocks that are supposed to be double-jumped onto are a little too high, causing one to have to attempt to jump onto them multiple times. Often, they actually require a short running jump to get onto, or need to be jumped onto at an angle, instead of head-on, or from the side. The camera can cause some problems, but is usually fixed by running around with the targeting mode engaged, so that the camera can be controlled by the Wii remote.
All in all, the game can be fun, if you forgive its design faults. A good strategy to avoid extensive frustration with this game is to play a level, then put the game away for a while, and then come back and play another level later on. Despite its graphics and theme, its design flaws make it suited more for older gamers than children.
