It says Klax and Marble Madness, so where's all of Marble Madness?
The graphics of the game sport the Arcade versions. While this does give a nostalgic feel, the graphics in todays standards wouldn't hold that much attention to many people, but I've got to admit that they nailed the arcade like of it down perfectly.
Just like with the graphics, the music and sound effects come from the Arcade versions. While they are good at some parts, overall, it's just something that won't amaze you in any way, nor will it just anything epic. But overall, it's still a decent job by having the arcade sounds port over to the Gameboy Advance. Also in Klax, the female announcer is still intact, so that may be something salvageable.
Marble Madness to this day is still a good time killer if you want to have a quick puzzle or race fix. However, not even this port could do this right. The tracks in Marble Madness got a huge downgrade. Not everything is there, and even some parts of the tracks were taken out, such as the animations of certain parts of a track. But what makes Marble Madness so bad is that the final 3 tracks of the game were cut off. You read that right. There are only three levels in this port. I don't know why they cut out the final 3 levels, but it certainly lost its appeal because of that.
Klax, on the other hand, is still as fun and addictive as ever. Basically, you have colored tiles that roll down a conveyor belt. You catch these tiles on the platform you control, and you dump them down below you. The key is to get three of the same colors to line up either vertically, horizontally, or in diagnols. It may sound simple, but the sheer joy of Klax is that in order to get higher scores, you need to have a set strategy, such as where to place a useless color tile, which color tile to let drop from the conveyor belt, and some other aspects. Because of this, Klax still remains a favorite among many among the puzzle genre. There are three types of Waves you can select from, each with their own requirements to beat the level.
All in all, if you're going to pick this up, simply do it for Klax, because Marble Madness is not the game it used to be because of those three levels being cut off, as well as certain animations not being there. It's a bad port, with Klax as its only savior.
