Short answer. HELL YES.
This game is not too hard to control. People who tell you that just haven't sat around and played with it enough. Once you get used to it, its actually quite inituitive. You have to remember, you aren't controlling the monkey, just the platform.
The first 10 levels took me FOREVER to get past, but I just kept at it. I've gotten to like level 51, each island has 20 levels, 10 easy and 10 hard, and I'm on hard on the third island. But I've replayed the first levels several times demoing it to people and I can beat the first 20 levels without dying at all.
It requires slight movements most of the time. People who are crazily moving the controller will have problems. It's a beautiful game and really fun once you get the hang of it. It just requires patience, but if it was so easy you could beat all 110 levels in one sitting, what would the point be?
In short: no.
It is WAY too hard, and you have to listen to the music on the game, if your going down the road listening to music and want to play it the music will turn off. If I had the option of buying it again I wouldn't, it too hard to control (way too sensitive) and to keep the ball still you have to hold the phone at an awkward angle (imo)
I don't think it was worth the 10 bucks. Like others said it is too hard to control and the angle isn't flat to keep the ball still, it is slightly leaned toward you, makes it hard to find.
Of all the games so far I have to say trism (http://appstorefeed.com/apps/Trism/) is the best one out now. It's a puzzle game that incorporates touch (to move the pieces) and motion (to determine where they will fall to fill in the gaps). You basically just match the triangles up by color but there are obstacles that come up and combinations to score more points.
If you're looking for something to kill time the $5 bucks is better spent on this than on super monkey ball in my opinion.
