I saw that in the top speed runs on Any% NG+ the speedrunners only had a select few items in the shop that they had purchased. I did not have the foresight to do such a thing so I was wondering if there was a way to reset the shop to allow me to have the same advantage that they had.

Dont think so. Got to start a new account or delete ur save file unfortunately.

You would have to turn off cloud.

Under resources on the discord. Ask about save swapping. I remember reading something about save swapping for PC. Could have been tripping though. Using discord and asking about it wont hurt though.

Do you know the name of the discord?

Within the list to the left, somewhere under leaderboard

thanks, really appreciated.
