Fun, but some control problems.
A very charming title, and true enough to the nature of cats! There were a couple of problems that I discovered while playing, though.
Firstly, as mentioned in other reviews, the matter of strings being created at the start of the level is an issue. It sends a mixed message overall: the times pumpkin urges the player to hurry to improve their score, while the string being drawn so easily forces a player to slow down if they want to gain the 100 point bonus after the level. I'd suggest using a different binding to creating strings as a fix, such as a combined key+mouse binding, like Shift+Mouse1.
Secondly, controlling the movement of the cats while hooked was hopeful at the best of times and pure luck at the worst. I found myself frantically dragging the mouse around (and thusly making strings in annoying places, only making it worse), trying to get a particular cat around a branch or enemy. Whether or not this was intentional, I'm unsure. I leave it to your judgement.
