Here great game, graphics, gameplay, level design ... but very difficult
you die dozens of times (at least) before finishing levels ... this is the good old "die and retry"
if you are not perseverant and you do not fight do not buy it you will have spent 45th for nothing
I am the 2nd world and I can already more .... but I fight for the finish!
you thought the last 2 Super Mario 3D worlds difficult world .... they are nothing compared to all the levels of this game ...
GOOD LUCK
