Amazing
Some levels became a bit repetitive, and i really hate those fat cats >.<
Graphics looks really nice, and its a bit tricky to get use to the controls, if i try to click on the cats or to double click on Sally and i miss, i end up making a string in the wrong place holding back the cats and erasing any other i had before, i ended up juggling cats all over a few times.
Besides that the controls are good once u get used to it, it would be nice if the arrows that show up when u pull higher or lower a cat also showed how much strenght its using on it, bigger or smaller arrows depending on how much u push them.
Also strings are life savers if u have good reflexes, it would be good if there was some king of limit to how many or how fast u can make strings in a row. Like X amount of strings per level or if you had to wait for some bar to fill if u use them to many times.
The dificulty is... not really hard, but challenging, and thats good.
