Submission Details

Value Curve Scores

Immediate Visual Readability
The game's core objective, player state, and immediate dangers are instantly understandable through visual cues alone, without text or tutorials.
Primary: 5
Secondary: 3
Tertiary: 2
New: 5
Preserve · Dominant: Primary · Persona Fit
Rationale: We had several issues in past games that the persona doesn't understand the game. They can control their character and give commands but they have a hard time understading what to do and why. E.g. Egg.io players can move, shoot but they don't understand the area coverage and the winning criteria.
Self-Generated Obstacle & Difficulty
Player success directly and visibly creates the primary obstacle and increases the challenge within the current run, making each decision more dangerous.
Primary: 4
Secondary: 0
Tertiary: 2
New: 4
Preserve · Dominant: Primary · Retention
Rationale: Conflict is very clear and inevitable, also doesn't create any sense of injustice or frustration when they lose (i lost because i am good).
Frequent Run-Based Upgrades
Players receive frequent, impactful upgrade choices during a run that significantly alter gameplay and strategy for that specific session.
Primary: 0
Secondary: 4
Tertiary: 3
New: 4
Create · Dominant: Secondary · Persona Fit
Rationale: The frequent sentiment of progression is important and this makes it frequent and very visible. This will be created using the simple Upgrades sytem we already have in Unity projects - almost no coding.
Visually Satisfying Collection & Progression Feedback
Collecting items and progressing through gates is accompanied by immediate, energetic, and visually spectacular feedback (e.g., bright effects, beat-synced explosions).
Primary: 1
Secondary: 3
Tertiary: 4
New: 3
Raise · Dominant: Tertiary · Persona Fit
Rationale: The game builds on top of snake mechanics but with visuals of pac-man 256 that is more modern, unique and tailored to a younger audience. The visuals are already set and have several good assets already present on the vault.
Short, Self-Contained Room Challenges
Gameplay is structured into distinct, quickly completable rooms or segments, each presenting a clear, immediate objective.
Primary: 0
Secondary: 4
Tertiary: 1
New: 4
Create · Dominant: Secondary · Persona Fit
Rationale: easy to understand challenges is essential for the persona. we had several issues with readability of the context in other games. Also, it is simple enought to add in the levels without complicating the design.
Clear Short-Term Goals & Milestones
The game constantly presents players with easily identifiable, achievable short-term objectives (e.g., 'open the next gate,' 'clear one more room').
Primary: 2
Secondary: 3
Tertiary: 2
New: 4
Raise · Dominant: Secondary · Retention
Rationale: Bite-sized goals gives that "just one more" sense because it feels like it can be done in a few seconds / minutes. Longer goals make the player pause when he knows it will take too long. This system is already present in the old Hi Fi Snake from the vault

Deterministic Violations

No deterministic violations.

AI Result

The Phase 4 value curve and ERRC decisions are coherent and well-justified. All attribute score reviews are clear, and all curve checks pass, indicating a strong and actionable design direction that aligns with project goals and constraints.

Score Reviews

Immediate Visual Readability
CLEAR
The primary reference score of 5 for Snake is plausible, and the new score of 5 with a 'preserve' action is coherent. The rationale directly links to persona fit and past project issues, providing concrete justification.
Self-Generated Obstacle & Difficulty
CLEAR
The primary reference score of 4 for Snake is plausible, and the new score of 4 with a 'preserve' action is coherent. The rationale clearly explains the player experience and lack of frustration, which is concrete.
Frequent Run-Based Upgrades
CLEAR
The secondary reference score of 4 for Archero is plausible, and the new score of 4 with a 'create' action (from Snake's 0) is coherent. The rationale highlights the importance of progression and explicitly mentions using existing Unity systems, demonstrating production awareness.
Visually Satisfying Collection & Progression Feedback
CLEAR
The tertiary reference score of 4 for Pac-Man 256 is plausible, and the new score of 3 with a 'raise' action (from Snake's 1) is coherent. The rationale clearly states the visual inspiration and confirms the availability of existing assets, mitigating scope concerns.
Short, Self-Contained Room Challenges
CLEAR
The secondary reference score of 4 for Archero is plausible, and the new score of 4 with a 'create' action (from Snake's 0) is coherent. The rationale links to persona needs for readability and emphasizes the simplicity of implementation, which is concrete.
Clear Short-Term Goals & Milestones
CLEAR
The secondary reference score of 3 for Archero is plausible, and the new score of 4 with a 'raise' action (from Snake's 2) is coherent. The rationale explains the 'just one more' loop and confirms the system's presence in the vault, demonstrating production feasibility.

Curve Checks

P4_REFERENCE_SCORE_PLAUSIBILITY
PASS
The reference scores for all attributes are plausible based on the provided Phase 2 evidence, Phase 3 pitch, Phase 3.5 attributes, and catalog metadata for Snake, Archero, and Pac-Man 256.
P4_DIFFERENTIATION
PASS
The new concept target scores effectively differentiate from the Primary Reference (Snake) by creating or raising scores in 'Frequent Run-Based Upgrades', 'Visually Satisfying Collection & Progression Feedback', 'Short, Self-Contained Room Challenges', and 'Clear Short-Term Goals & Milestones', while preserving Snake's core strengths. This creates a focused and distinct design direction.
P4_DOMINANT_REFERENCE_FIT
PASS
All dominant reference choices align logically with the highest reference scores or the most relevant reference for the intended ERRC action and new score, clearly indicating which Trinity reference is leading each attribute.
P4_RATIONALE_CONCRETENESS
PASS
All rationales provide concrete, production-relevant reasons, including links to persona fit, existing systems/assets, and specific player experience outcomes, rather than generic claims.
P4_WATCHABILITY_IMPROVEMENT
PASS
The 'Visually Satisfying Collection & Progression Feedback' attribute (attr_4) is raised from a primary reference score of 1 to a new score of 3. Its support tags include 'watchability', and the rationale explicitly mentions 'visuals of pac-man 256 that is more modern, unique' and 'several good assets already present on the vault,' directly contributing to visible spectacle and clip-worthy action.
P4_RETENTION_IMPROVEMENT
PASS
The 'Frequent Run-Based Upgrades' attribute (attr_3) is created from a primary reference score of 0 to a new score of 4, with 'retention' as a support tag. Additionally, 'Clear Short-Term Goals & Milestones' (attr_6) is raised from 2 to 4, with its rationale emphasizing the 'just one more' loop, both materially improving progression and return incentives.
P4_IP_PERSONA_FIT
PASS
The value curve, with its emphasis on immediate readability, self-generated challenge, frequent upgrades, satisfying feedback, short challenges, and clear short-term goals, consistently aligns with the 'Hi Fi Snake' concept and the Web Gen-Z Drifter persona's needs for low-friction, immediate, and bite-sized experiences.
P4_SCOPE_DISCIPLINE
PASS
All attributes with raised or created scores ('Frequent Run-Based Upgrades', 'Visually Satisfying Collection & Progression Feedback', 'Short, Self-Contained Room Challenges', 'Clear Short-Term Goals & Milestones') include rationales that explicitly reference existing systems, available assets, or simplicity of implementation, demonstrating strong scope discipline.
P4_DAILY_RETURN_ALIGNMENT
PASS
The curve's emphasis on 'Short, Self-Contained Room Challenges' (attr_5), 'Frequent Run-Based Upgrades' (attr_3), and 'Clear Short-Term Goals & Milestones' (attr_6) directly supports the daily return hook of a 'new three-room remix with a special modifier' and its completion for rewards.
P4_ERRC_COHERENCE
PASS
The combination of 'preserve' actions for Snake's core mechanics, 'create' actions for Archero's progression and structure, and 'raise' actions for Pac-Man 256's visual spectacle and Archero's goal setting forms a coherent and well-justified design direction for the project.
