See first video and world 4 part 1 for all details.
0:03 Land of the Dead: Simple but still hard level to lead you into World 5. This level gets carried away with precise jumps AND attacking you with projectiles at the same time.
3:12 Beautiful Oasis: Because we needed one. There's also a bit of swimming in this level, and some blue shell less Koopas later on.
7:02 The Dragon House: Please note that this house has no dragons nor does it have references to dragons. What follows is a ghost house with quicksand, and quite a bit of P-Switch running/ferrying, to find the right path. It's very tricky to pull all of this off correctly, plus some enemy placements are just sneaky.
