If you dont want to know the secrets of the levels, dont look any farther.

WORLD 1 LEVEL 1
Fairly Simple level. Go forward past the first bridge and hit the ? Block. A Tanooki leaf is inside. Advance forward to the rope. Grap the star coin and go down. Jump the little white fence and break the box at the end. Go through the tunnel for a 1up. Jump out of there and go on the rising platforms to the checkpoint flag. Go to your left and climb the tree. Get on the platform and go down the pipe. Grab the star coin and jump out. Go back to the checkpoint flag. Go to your right and jump the little fence. dont worry theres a 1up there. Go back to the checkpoint again and then go straight to the trees in front of you. Climb the one on the right for a tanooki leaf. Go into the tunnel thing and smash the brick past the goomba. A spinner will come out. Keep hitting it with your tail and jump to the top. grab tge 100seconds and jump off. look for Toad in the binocular things then climb the hill. jump onto the Musical Block and go forward. climb the rope to the star coin and hit the ? block. another tanooki leaf. Keep going and the flagpole is right there. Level 1 complete.

WORLD 1 LEVEL 2
Underground Level Pretty Easy.
Many people wonder why theres a hole behind you why you first start. I dont know why. XD
Go forward and dont kill yourself with the giant ball. Get the middle ? box for a Fire Flower. Get it. Now go and kill the inkplants. if they spit on your screen, blow into the mic. to get it off faster. Get on the rotating platform and grab the star coin then fall into the hole. theres a pipe with a 100seconds and some coins. Go out the other end. Go forward and kill the goombas in your way. Grap the checkpoint flag and keep going. grabthe coin. it leads to more coins. Now go through the passage and get the coins on the wall. now hit the single sized ? block for a fire flower if needed. go forward and grab the star coin above the moving platforms. kill the inkplant. Advance to the bridge and dont get hit. Now hit the stone thing in the corner with some fireballs to get coins. Go on the little ramp and get the star coin past the ink plants.
1: Go through the green pipe and get the flagpole.

2: go back to the the ? blocks onthe wall and jump up to the top. keep running straight to the orange pipe. Its a warp pipe to WORLD 2
Also! the first koopa that appears by the ? blocks there, hit it once then jump on it again. if its right on the Tri sized ? and the wall, you can get unlimited lives by jumping on it.

Thats all for this time!
World 1 Level 3-4 is next.
After that...
World 1 Castle and bonus stuff.
