- Distinguish bites from line overload through more than one feedback channel.

## How it works

Harvesting trades combine site and tool choices with reading target behavior and timing resource collection.

## Variants

### Mechanic variants

<a id="t129-variants"></a>

- Bait selects a likely catch category. <a id="t129-v1"></a>
- Tension requires modulating the pulling force. <a id="t129-v2"></a>
- Tracks narrow the target search area. <a id="t129-v3"></a>
- Harvest limits preserve site recovery. <a id="t129-v4"></a>

## Design example

An angler loosens the line during a surge and reels in during a brief pause in resistance.

Prototype check: Test distinct bite and overload signals, including an alternative to mandatory vibration feedback.

## Context and limits

Activity simulators turn observation, operation sequences and limited tools into a testable work task. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.
