This is a really great rental it just doesn't have enough levels to warrent a purchase. The game does have a great rewarding system for collecting items and winning gold medals for each level. To get a gold medal you have to beat the required time to get it. The only problem is the camera is fixed and it's really poor for going fast. Often times I fell off trying to get gold medals because I couldn't see far enough ahead. The difficulty is a little uneven too. The first 3 worlds a really easy but the last couple a extremely hard and you'll fall often dozens of times. The levels are fun though it's just the camera is a little off. If they used the camera system from Mercury Meltdown and added about 30 levels I would of given this game a 9.
This game was very fun, and uses the wii-mote very effectively. It by far outweighs any other marble games for the NES, because this one doesn't rely on directional arrows, but relies on the movement of the wii-mote (so you get more control). It's very short, but can be made to be more challenging based upon the type of ball selected, and attempts to beat your own time score. The secret levels are o.k. Some are fun and experimental, but others are just there for fun (with little challenge), so the extra levels can sometimes feel like a waste, like they were the levels that just didn't make the final cut. But, it's got a basic/classic board-game feel, where you can replay over and over, because the challenge is in your hand controls, not the levels.
That's exactly what this game felt like. A waste of my time. Its so short and unappealing it's pathetic. I wasn't even playing for two hours and I had nearly unlocked all the levels with silver medals and most of the green jewels. I had almost all of the balls before I just decided to stop wasting my time with it. It wasn't a challenge.
The levels are interesting but the more complex they get the more annoying it is to try and control the ball. First off, there are no real physics in the game. It's based on your ball. Most of the levels are just designed to be difficult and not a challenge in complexity but patience. If you actually want to waste 20 minutes figuring out how to get through a difficult level with a decent trophy by trying it over and over again be my guest. If you want to play this game just to play through, it's almost a waste of a rental. It will take between 3-5 hours to play through every level of this game including the secret levels. If you want to waste your time actually trying to get the gold medals, I have to say it's simply not worth is.
The game was fun at first but the controls eventually got to me. They are not well honed. In fact they are loose and slippery. The control doesn't keep good balance and it's very hard to control rolling your ball in most situations. I like the game from the puzzle standpoint but from that same point, it wasn't a very good puzzle. The concept wasn't difficult, playing it was.
