A crucial element that wasn't mentioned here was the lack of play-testing. Having a dozen people play the game and give feedback would have informed the makers that it was too hard, and where.
It ties in with the lack of time and resources too -- if you don't structure your development to have time to do user testing, you won't magically find that you have time to do it at the end, either.
