YES! Finally a "break the block" game for a handheld that works!

User Rating: 9.5 | Arkanoid DS DS
There have been several attempts to bring this sort of game to the DS (nervous brickdown/brick 'em all to name a couple) but this is the first one that really works.

The Good:
Controls are excellent whether using the stylus or the d-pad(which is my preference) the vaus (bat really) moves smoothly and consistantly accross the screen.
The gameplay is classic arkanoid (I spent hours playing Arkanoid 2 - the revenge of Doh on the atari ST when I was a kid) with the concept of choosing a route through to the end, not after each level but after each set of 5 levels. Great gameplay offering multiple routes to the finish and making re-play value immense - I haven't seen all the levels yet!
There is also a nice twist for gaming on the go - each level has a secondary objective accessed in "quest" mode. Once the level has been played in standard "clear" mode it is availble in quest - however the twist is the objective is different. For example, clear all in 45 secs/clear a certain colour in 30 secs/hit a certain brick with only 5 bounces from the vaus etc. This are an ideal way to practice and to hit that all important "5 mins waiting for the bus" scenario.
On-line multiplayer - only good thigs to say about this, sometimes have to wait to find an opponent but once in a game it is smooth with the ability to disrupt the opponents game with "power downs". Lots of fun and re-playability - plus an online score board!!

All this and sold in the bargin price bracket.

The bad:
About the only negative thing I can think of to say is that the actual playable screen is a little narrow and the split screen sometimes cause you to "lose" where the ball is coming from.

Overall:
What are you waiting for!!!!
