An extract from the WiiWare World review of The Incredible Maze:
"The idea is so simple in concept that it's hard to believe the developers managed to screw it up so severely. Using either the Wii Remote or the Balance Board to carefully tilt the stage, you merely attempt to direct a marble through a variety of mazes to reach the goal. Unfortunately even this most basic function is flawed. The Wii Remote controls are downright atrocious due to twitchy, unforgiving sensitivity. Fortunately, the Balance Board is much more serviceable thanks to less finicky (yet still unstable) tilting controls. Additionally, flicking the Wii Remote or pressing A while standing on the Balance Board causes the marble to jump, but this mechanic is so inconsistent that we have to wonder why they even bothered to add it in. On the occasions where jumping actually works to your benefit it undermines the whole maze concept because you are just able to jump a few walls en route to an easy goal. So what we're left with is a game that is practically unplayable with a Wii Remote alone and otherwise moderately broken.
For what it's worth there is a modest selection of levels. However, even if the gameplay was sound this collection of poorly-designed stages wouldn't be worth the trouble. Part of the problem is that they are haphazardly strung together with little consideration for difficulty progression, resulting in a game that wildly jumps from ridiculously easy to seemingly impossible before abruptly screeching to a halt after the 30th stage. At that point you'll unlock a Time Attack mode which challenges the player to use efficient jumping to complete the stages in a given time, but since jumping is so unreliable it is hardly worth the bother."
