Submission Details

Value Curve Scores

Visible HP Numbers & Damage Feedback

Enemies clearly display their health as numbers, and hits provide satisfying, immediate visual and numerical feedback.

Primary: 5

Secondary: 1

Tertiary: 1

New: 4

Reduce · Dominant: Primary · Persona Fit

Rationale: Gives a very clear and direct progress feedback to players. It is easy to assess, see which enemy is stronger also how much is left. For Web players we will do the same and make the "health progress" very visible the only difference is that we have chickens and not forms as enemies which makes the numbers a little less proeminent.

Territory Control Visuals (Blue vs. Red)

The game clearly communicates progress and conflict through the visual dominance of player (blue) vs. enemy (red) color on the battlefield.

Primary: 2

Secondary: 4

Tertiary: 2

New: 3

Raise · Dominant: Secondary · Retention

Rationale: Paper.io is all about the coloring of the field. We will make it very important, progression is based on coverage %. But, the game is also about killing the other chickens and making sure they don't reach your eggs.

Simple, Immediate Stat Upgrades

Progression involves choosing from a small set of clear, flat stat upgrades (e.g., damage, reload, speed) that immediately make the player feel stronger.

Primary: 4

Secondary: 2

Tertiary: 5

New: 5

Raise · Dominant: Tertiary · Persona Fit

Rationale: Primary and tertiary reference use very simple set of clear upgrades. We will also build on this with upgrades purchasable after every wave and can be leveled up endlessly.

Snackable, High-Action Sessions

Gameplay sessions are designed for short bursts (2-5 minutes) with constant, readable action and clear objectives, suitable for quick play on web browsers.

Primary: 5

Secondary: 4

Tertiary: 5

New: 5

Preserve · Dominant: Primary · Watchability

Rationale: As the references, the objective is clear the area of chickens while making sure they paint as little as possible. Everything very readable. Each wave is very fast 30-60 seconds but they keep coming. Player can stop at any wave and come back later where they left.

Visually Dramatic Comeback Moments

The game features moments where a single player action can dramatically shift the tide of battle, creating highly watchable and shareable visual spectacles.

Primary: 5

Secondary: 5

Tertiary: 5

New: 5

Preserve · Dominant: Primary · Watchability

Rationale: The defense side of the game make it very important to look at chickens approaching the player's nest (end of path). Killing that chicken in the last minute is what can turn the tide of battle. Just like moving the canon to the side in the primary reference.

Almost no onboarding

The simple controls - left and right only. Is pretty straight-forward and doesn't require a lot of tutorial and/or explanation

Primary: 4

Secondary: 2

Tertiary: 3

New: 4

Preserve · Dominant: Primary · Persona Fit

Rationale: Just as the primary reference, the player just needs to move the chicken side to side and stop to fire. Very simple, very direct. No virtual joystick, no complex input, nothing. Tap / Click and the chicken moves there.

Deterministic Violations

No deterministic violations.

AI Result

Phase 4 value curve evaluation passed. All reference scoring, dominant reference choices, ERRC derivations, and rationales are plausible, concrete, and aligned with project parameters.

Score Reviews

Visible HP Numbers & Damage Feedback

CLEAR

Primary reference (Cannon Blitz) scored at 5 baseline; target reduced to 4 with clear rationale that chicken enemy design slightly softens heavy geometric number prominence while preserving damage readability.

Territory Control Visuals (Blue vs. Red)

CLEAR

Dominant reference set to secondary (Paper.io 2 at score 4); target raised from primary score of 2 to 3 with concrete rationale explaining field coverage percentage alongside enemy wave clearing.

Simple, Immediate Stat Upgrades

CLEAR

Dominant reference set to tertiary (Diep.io at score 5); target raised from primary score of 4 to 5 with clear plan for wave-end stat purchasing and endless stat scaling.

Snackable, High-Action Sessions

CLEAR

Preserved at score 5 matching primary reference with concrete explanation of 30-60 second wave structure and instant session pause/resume.

Visually Dramatic Comeback Moments

CLEAR

Preserved at score 5 matching primary reference with high watchability rationale based on last-second chicken pops near the nest.

Almost no onboarding

CLEAR

Preserved at score 4 matching primary reference with simple tap/click horizontal movement controls requiring no complex tutorial.

Curve Checks

P4_REFERENCE_SCORE_PLAUSIBILITY

PASS

All reference scores logically map to the characteristics described in Phase 2 context and Phase 3.5 reference roles.

P4_DIFFERENTIATION

PASS

Target curve differentiates from Cannon Blitz by reducing raw HP number dominance (attr_1) while elevating territory control visuals (attr_2) and upgrade depth (attr_3).

P4_DOMINANT_REFERENCE_FIT

PASS

Dominant reference assignments correctly reflect which Trinity member leads each attribute (attr_1, attr_4, attr_5, attr_6 -> primary; attr_2 -> secondary; attr_3 -> tertiary).

P4_RATIONALE_CONCRETENESS

PASS

Rationales provide tangible design specifics (e.g., tap/click horizontal control, 30-60s wave bursts, coverage %, post-wave upgrades).

P4_WATCHABILITY_IMPROVEMENT

PASS

Raising Territory Control Visuals (attr_2) from baseline score 2 to 3 adds dynamic blue vs. red color pressure to the battlefield spectacle.

P4_RETENTION_IMPROVEMENT

PASS

Raising Simple, Immediate Stat Upgrades (attr_3) from baseline score 4 to 5 strengthens the session-to-session power loop.

P4_IP_PERSONA_FIT

PASS

High scores in snackable sessions, low onboarding, and immediate upgrades directly serve the Web Gen-Z Drifter persona.

P4_SCOPE_DISCIPLINE

PASS

Raised scores rely on straightforward visual coverage math and simple numerical stat increments, staying well within low-friction web scope.

P4_DAILY_RETURN_ALIGNMENT

PASS

The wave-based upgrade loop (attr_3) and bite-sized sessions (attr_4) support repeat daily visits alongside the Phase 3 daily chest hook.

P4_ERRC_COHERENCE

PASS

ERRC derivations (reduce on attr_1, raise on attr_2 & attr_3, preserve on attr_4, attr_5 & attr_6) mathematically match Primary Reference score shifts and form a coherent core loop.
