Celeste - 1UP Achievement (Trophy Guide) Easiest way
In this video you will see how to get 1UP Achievement.
Also copied the guide here:
To get the achievement, you will need to get the so-called 1UP. To do this, you will need to collect at least six berries, avoiding prolonged contact with the ground (you can touch the surface only once), thereby not allowing them to be counted ahead of time. After the required number of berries are collected, you can stand on the surface and get the achievement. This can be done in the first
chapter (Forsaken City).
