Keep the Fish in the Zone
The fish darts around a bar; keep your catch zone on it to land it.

01The core loop
Action → feedback → next choice- 01Fish starts moving
- 02Move your zone to follow
- 03Progress fills
- 04Fill it to land
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
A hard fish darts up and down; the catch zone is 20% of the bar and progress is 60%.
- T2
Turn 2 · The player chooses
The player switches to light taps to hover mid-bar rather than chasing.
- T3
Turn 3 · The feedback
The fish swings back through twice, progress hits 100% and a 'Perfect' tag appears.
- T4
Turn 4 · The next decision
The catch is higher quality, and the player eyes a bobber that widens the zone.
How it plays
In a minigame, the fish icon moves erratically while you press and release to control a catch zone. Progress rises while the fish is inside and falls when it escapes. Fish difficulty sets speed and erratic jumps, and gear can widen the zone.
What the player weighs
- Chase precisely vs. sit centered and wait
- Gear for a bigger zone vs. gear for better quality
02Start small

03One mechanic, different implementations
Stardew Valley
A green bar rises with the button and falls with gravity while the fish moves in a vertical meter; fishing level and tackle change bar size and progress speed.

Graveyard Keeper
Fishing also uses a follow-style minigame where you keep the fish inside a target area for a while; I'm not certain of the exact controls.
The difference worth noticing
Stardew's minigame has physical feel and a growth curve; Graveyard Keeper treats fishing as a lighter side activity.

04What could you combine?
Give each species a hidden movement pattern players can learn by observation to predict its next jump.

The Bite Window
A bite lasts a moment; strike too early or late and you come up empty.

Managing Line Tension
Pull too hard and the line snaps; too soft and the fish escapes.
