File Stamps

In Celeste, your file has Stamps that appear for achieving certain levels of completion. These stamps vary from beating the game to collecting every Strawberry. A list of Stamps can be seen below.

Completion Stamps
These Stamps can be collected by passing certain thresholds in Celeste.

The Summit
This is the main stamp in the game, and most likely the first one most players get on their save file. It looks like the flag that you see on The Summit. It is achieved by completing Chapter 7: The Summit.

Farewell
After beating Chapter 9: Farewell, you get a little bird stamp on your save file, signifying that you beat all 9 Chapters in the game.

Cassette Tapes
If you collect all 8 Cassette Tapes in every chapter, you unlock this stamp. Cassette Tapes unlock B-Sides.

Pink Crystal Heart
To get this stamp, you need to collect every Blue Crystal Heart (found in each A-Side Chapter) and every Red Crystal Heart. (found in each B-Side chapter)

Yellow Crystal Heart
After collecting all 24 Crystal Hearts (including the C-Side Yellow Hearts), you earn this stamp.

Strawberry
After collecting all 175 regular strawberries, this stamp will appear on your file.

Golden Strawberry
After collecting all golden strawberries, you will earn this stamp.

Golden File
Although not a stamp, after 100%ing the game, your file will turn golden.

Editable Stamps
There are three specific Stamps in the game that appear on the side of your file instead of the file itself. Two of these can be turned on and off at will, and the other one requires a specific combination of buttons to unlock, and is permanently put on your file.

Assist Mode
When activating Assist Mode for the first time, you put this Stamp on the side of your file. It's image (insert image here) is a blue circle stamp with presumably angel wings on it, signifying that it helps the player when used.

Variant Mode
Essentially an extended version of Assist Mode, it creates a purple circle stamp with a pencil on it, meaning you can edit how the game reacts to certain things.

Cheat Mode
Unlocks every level and alternate sides, while adding a little green stamp that says "Cheat Mode" permanently on your save file, with no way to deactivate it unless you make a new one.
