Wizorb is basically an Arkanoid/Breakout clone. It's pretty decent, but like other games in this genre, the devs like to design maps where your powers are of limited use (typically placing blocks behind indestructible objects), and thus you spend several minutes trying to get that one last block.
The graphics have a charming old school 8-bit look, and are well-animated. The music is... forgettable.
The speed of the paddle is defaulted to 1. I highly recommend changing that to 3 when starting, or you will quickly find the ball outpaces you. Even then, it doesn't move fast enough.
Despite being marked as having full controller support, it didn't recognize my PS2 controller, but Joy2Key solves that, as usual. You'd think mouse control would work well, but for some reason the paddle actually moves slower than using a keyboard, thus mice are less than ideal.
I think the biggest problem with the game is how much potential was wasted. It presents some cool RPG-like features like walking around in town and gathering cash to buy stuff, but most purchases do little for you. It would have been awesome if you could gain levels and gain permanent items, and actually feel a gradual progression of becoming stronger. But as usual, one death and you're back to square one. And of course there's the near non-existent story.
The best quality of the game is perhaps how inexpensive it is - less than $1 on a sale. Is it worth it? Well considering I finished in about an 3 hours with little replay value, it's... hard to say. If I had more fun I'd easily recommend it. I'd be willing to bet I could find, or even make a Breakout clone that could hold my attention better.
