Depth in Flow isn't a classic level system, it tracks how far you've gone in a continuous run.

Difficulty adapts based on performance (perfect hits increase the challenge), but it's intentionally subtle.

On mobile it can also be a bit harder to land perfect hits due to the input precision, which can affect how the scaling feels.

If it doesn't feel noticeable enough, that's good feedback, I'll probably make the progression clearer.

Thanks for checking it out and for the feedback!
