Not sure why some ppl are talking about lag in the pc version . I have everything on and the game runs flawlessly no lag no tearing. Beat the first world yesterday before heading to work and I feel it's superior to the first so far . Multiple pathways, unlockable costumes , and secret 8 bit worlds. Only negative to me is the checkpoints on boss fights . While you can simply jump over them in the regular levels , you can't in the different phases of the boss fight .
