Where can i put the cheat password
If you got rid of all the plants in the middle path and slashed down the vines in the way, you just have to be quick about getting to the top of the map. I say immediately start moving after you click yes and book it all the way up. Always having dash on helps you with that, as you don't have to hold the dash button to get up there. I've made it up plenty of times, just gotta be quick.
