Beautiful game, but I feel only frustration in the later levels ...

The game has beautiful graphics and Soundtrack (two stars), and you can play four is certainly an added value (one star). But the stamp (who came up with this nonsense?), The Invincibility - mode (after a few deaths) for the little ones and the green star I find forced on, why? Quite simply, the game is too hard to achieve really 100%. The create just to collect all the green star and stamps (you do not just pick up everything, but should also complete each level with any character once play). For this I do not feel like, because at the end (special world) are the levels just frustrating (here Super Mario Galaxy is better). But the levels nerves on time, here 30 seconds and here again 10 seconds. Later there is a level that you should complete in just 100 seconds. If I want to sweat, I go out jogging. I sold the game. Nevertheless, a lot of fun the other, looking for a challenge.
