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: 2
Secondary: 4
Tertiary: 3
New: 4
Raise · 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: 3
Secondary: 4
Tertiary: 2
New: 4
Raise · 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: Primary · 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 submission requires iteration due to an incorrect dominant reference assignment for one attribute, which also caused a failure in the P4_DOMINANT_REFERENCE_FIT check. All other attribute score reviews are clear, and the remaining curve checks pass, demonstrating a generally coherent design direction and well-justified decisions.

Score Reviews

Immediate Visual Readability
CLEAR
The reference scores are plausible, the dominant reference (Primary/Snake) is appropriate for this attribute, the 'preserve' ERRC action is coherent, and the rationale is concrete, linking to persona fit and past project experience.
Self-Generated Obstacle & Difficulty
CLEAR
The reference scores are plausible, the dominant reference (Primary/Snake) is appropriate for this attribute, the 'preserve' ERRC action is coherent, and the rationale is concrete, explaining player perception and linking to retention.
Frequent Run-Based Upgrades
CLEAR
The reference scores are plausible, the dominant reference (Secondary/Archero) is appropriate for this attribute, the 'raise' ERRC action is coherent, and the rationale is concrete, linking to progression and production feasibility with existing systems.
Visually Satisfying Collection & Progression Feedback
CLEAR
The reference scores are plausible, the dominant reference (Tertiary/Pac-Man 256) is appropriate for this attribute, the 'raise' ERRC action is coherent, and the rationale is concrete, linking to persona, modern visuals, and existing assets.
Short, Self-Contained Room Challenges
CLEAR
The reference scores are plausible, the dominant reference (Secondary/Archero) is appropriate for this attribute, the 'raise' ERRC action is coherent, and the rationale is concrete, linking to persona fit and production simplicity.
Clear Short-Term Goals & Milestones
ITERATE
The attribute 'Clear Short-Term Goals & Milestones' (attr_6) was sourced from Archero (game_2) in Phase 3.5, and Archero's score (3) is higher than Snake's (2) for this attribute. Archero's contribution explicitly mentions 'constantly gives the player another nearby objective: clear one more room.' However, the submission incorrectly identifies Snake as the dominant reference ('primary').
Required fix: Change the 'dominant_reference_role' for 'Clear Short-Term Goals & Milestones' (attr_6) from 'primary' to 'secondary' to align with the attribute's origin and Archero's stronger contribution to this aspect.

Curve Checks

P4_REFERENCE_SCORE_PLAUSIBILITY
PASS
All primary, secondary, and tertiary reference scores are plausible based on the provided Phase 2 evidence, Phase 3 pitch, Phase 3.5 attributes, and catalog metadata.
P4_DIFFERENTIATION
PASS
The new concept target scores produce meaningful differentiation from the Primary Reference (Snake) by preserving its core strengths (Immediate Visual Readability, Self-Generated Obstacle & Difficulty) while raising scores for other attributes (Frequent Run-Based Upgrades, Visually Satisfying Collection & Progression Feedback, Short, Self-Contained Room Challenges, Clear Short-Term Goals & Milestones), indicating a focused evolution of the concept.
P4_DOMINANT_REFERENCE_FIT
FAIL
For 'Clear Short-Term Goals & Milestones' (attr_6), the attribute's source is Archero (game_2), and Archero's score (3) is higher than Snake's (2). Archero's contribution explicitly mentions 'constantly gives the player another nearby objective: clear one more room.' The submission incorrectly identifies Snake as the dominant reference.
Required fix: Change the 'dominant_reference_role' for 'Clear Short-Term Goals & Milestones' (attr_6) to 'secondary' to align with the attribute's origin and Archero's stronger contribution to this aspect.
P4_RATIONALE_CONCRETENESS
PASS
All rationales provide concrete, production-relevant reasons, often linking to persona fit, existing systems/assets, or specific design goals, rather than generic claims.
P4_WATCHABILITY_IMPROVEMENT
PASS
The 'Visually Satisfying Collection & Progression Feedback' (attr_4) is raised from a Primary Reference score of 1 to a new score of 3, directly improving visible spectacle and clip-worthy action, which aligns with watchability goals and the TikTok moment.
P4_RETENTION_IMPROVEMENT
PASS
The 'Frequent Run-Based Upgrades' (attr_3) is raised from 2 to 4, and 'Clear Short-Term Goals & Milestones' (attr_6) is raised from 2 to 4. Both materially improve progression, repeat-session value, and return incentives, directly supporting the retention loop.
P4_IP_PERSONA_FIT
PASS
The value curve coherently fits the 'Hi Fi Snake' IP and the Web Gen-Z Drifter persona by preserving core Snake mechanics while enhancing progression, visual feedback, and session structure, all of which are explicitly linked to the persona's needs and ManiMani principles in the rationales.
P4_SCOPE_DISCIPLINE
PASS
All raised scores are justified with rationales that reference existing systems, available assets, or design simplicity (e.g., 'simple Upgrades sytem we already have,' 'visuals are already set and have several good assets,' 'simple enought to add in the levels,' 'system is already present in the old Hi Fi Snake'), indicating good scope discipline.
P4_DAILY_RETURN_ALIGNMENT
PASS
The curve's emphasis on 'Short, Self-Contained Room Challenges' (attr_5, raised to 4), 'Clear Short-Term Goals & Milestones' (attr_6, raised to 4), and 'Visually Satisfying Collection & Progression Feedback' (attr_4, raised to 3) directly supports the daily return hook of a 'new three-room remix' rewarding 'rotating cosmetic piece[s]' with engaging feedback.
P4_ERRC_COHERENCE
PASS
The ERRC choices (all 'preserve' or 'raise') form a coherent design direction, maintaining the core identity of Snake while strategically enhancing progression, visual appeal, and session structure by drawing from Archero and Pac-Man 256, aligning with the overall project vision.
