I learnt that the difficulty of a tsumego, you solve in an applet, depends on the obviousness of the first move.
The first move in the 12-kyu-problems is pretty obvious, so is White's first answer and your reponse. White's third move needs calculation but I guess a lot of player will click until now and then start reading : D
In quite some of the problems, I fail, I suffer from a different habit: I read all the way without clicking and when I'm sure it works, I blitz through. When I read correctly and didn't get caught off guard by missed responses, I do good. Other times I fail 11-kyu problems ^^ Now I try to pace myself while clicking, checking if my line really works.
In the second problem the first move is rather not "vital-point-ish", which makes it harder for the trained eye (see Treasure Chest Enigma and the problem "solve in three days to be a professional" (
paraphrasing) ^^). Of course I read the capture first, too ; )
"Dead shapes" are a funny subject on their own, see the following problem:
