"This is an action game for non action people". Screw that, it needs more platforming elements and some serious skill to get through them to be enjoyable.
Oh, i'm sorry but not everyone likes to grind as much as you do.
"Oh, I missed that platform, lets try it again"
"Oh, I missed it again, lets try it one more time"
"Missed it AGAIN, this is getting on my nerves"
And after about 10 times this shit happens, most people would just leave the game or cheat through the level.
Think about this for a second- if it's going to be hard as balls for you, most of the people who play this game are going to find it impossible.
And what is this bull about portal 2 being easy? The last bits of every part took me some time to figure out, and the co-op was seriously hard at some points.
