"You don't just die for nothing. The screen follows you. So it doesn't cut off the level under which you die.
You don't have people jumping on your head causing you to fall into holes.
You don't have people zooming through the level leaving you behind.
You can actually focus on obstacles and make it through levels without dying a million times.
The sheer amount of things to get and the sizes of the levels make it a mario-fest in single-player mode. A good example of this is Level 9-8. So much to get it's like jumping in a pool of gold!"
I feel the complete opposite. All of these made the game more fun. I tried playing it single player and fell asleep (due to boredom).
