I think I nailed down why the last level I played bothered. Compare how long the level takes to complete, and the relatively low amount of... stuff, that you do. There is a very low amount of actual obstacles and stuff to navigate, and although the level might seem to be open ended it's actually really straight-foward. So it's like if the 'stuff to do' / 'time to finish' ratio was out of wack or something. http://talkhaus.raocow.com/viewtopic.php?f=3&t=14522
