The Erosion counter is a mechanic in .flow that affects several aspects of the game. The counter will generally increase after witnessing disturbing events and will also increase a small amount if caught by chasers. The higher the count is, the more damaged Sabitsuki will become, causing certain things in the game to be more distorted. It is also possible to lower the counter by paying for food and drink at the Sugar Hole or interacting with Oreko with the Diving Helmet Effect on.
Little Sabitsuki in the Parade Ward is also affected by the Erosion counter, as her condition will worsen the higher the number is. If the Erosion Counter is 100 or greater, the Rust Menu Theme can be obtained from her.
There are a couple ways to observe how high the Erosion Counter is in-game. The most immediately noticeable is in Sabitsuki's Room. As the counter increases, bloodstains will become present in the room, as well as other changes.
| Erosion Counter | Changes |
|---|---|
| 0 | None. |
| 50 | Blood present on the computer keyboard & by the bed. |
| 100 | Larger bloodstain appears by the bed. Interacting with Little Sabitsuki in the Parade Ward at this point will get you the Rust Menu Theme. |
| 150 | Another bloodstain appears on the wall beside the television. |
| 180 | Sabitsuki's computer is outfitted unknown equipment with red wiring. |
| 200 | Several smaller bloodstains are present on the north walls. |
| 250 | It is possible to trigger the Erosion Event. |
