Some of the aggravation comes from technical bugs, but mostly it is poor game play design. Mini-games with one or maybe two sentences to tell you the goal and rules. Illogical or unclear game goals and story. One of a very few games that I couldn't even finish the free demo because it was too irritating!
It is a rarity when I do not finish the trial version, but this one only got 20 minutes of my time. I was ready to quit after 10 or 15 but thought maybe it will get better. Wrong! Boring, simple and pointless game.
I was expecting a lot more from this game based on its rank of Game of the Year. I played 45 minutes of the hour long trial and will not even bother finishing the hour. I agree with all others who rated it with one star, but will say that I think the mini games are not explained well as to what the objective is (as opposed to being difficult). When it says "open the gate" as the objective, that is too vague. Do I get rid of all the balls or line them up or what? The main game is pretty much the same way. I am glad that I don't have to waste any money to find these things out.
