You need to press up in the dpad, there is a door up there :)
No, they're not allowed :) You need to start the game from a hard/soft reset when you do your attempts.
(& even if they were allowed, p-wings are not a guarantee of getting p-speed strats, flying slows you down, damage boosting & menuing makes you lose time & you'll need to burn all 28 p-wings)
If you warp from W2, you're going to select from W5-W7 & the WW is banned My routing idea is: Warpless W1 (you get a P-wing for 6-5), Warpless W2 but with all the bros (you get a cloud to skip 3-6), Warpless W3, 4-2, warp to W6, Warpless W6 up to 6-7 & warp again to W8 & finish the game. In the way you can collect the Hammer Suit or take the flower in 6-7, Navy, Hand 3 or 8-F.
Edit: in W1, you need the 2 whistles, because when you warp in W6 you keep in the same line from W5-W7, so you need another whistle in the Warp zone, to go to W8.
Hello, I was thinking about this new category since it can be a little challenging: Beat the game after getting the 3 anchors. You can get them by getting all coins in 2-2, 4-2 & 6-7.
