Quick text summary

Core Keeper scored 72/100 on Steam Analyzer — Good for a Open World capsule. Top priority fix: [title_readability] Increase the size and contrast of the Void and Voltage subtitle text so it remains legible at 231x87, or integrate it into the logo as a stronger lockup.

Capsule scores by dimension

  • Genre Clarity: 7/10 — Mining sandbox adventure clear enough. The chibi-style character with goggles and a tool, cave environment with stone archways, and glowing fire portal all suggest an underground action-adventure or mining RPG. The fantasy cave setting and character design communicate indie sandbox RPG reasonably well. At tiny size the character and fiery portal read as action-adventure but the mining/crafting sandbox nuance is harder to distinguish from a generic platformer.
  • Title Readability: 7/10 — Main title readable, subtitle struggles. Core Keeper uses a bold stylized font with blue and white coloring that reads clearly at full and small sizes, positioned in the lower-left against a relatively controlled dark stone background. The subtitle Void and Voltage is noticeably smaller and uses a lighter treatment that becomes unreadable at tiny size. At small and tiny sizes only Core Keeper survives as legible text.
  • Contrast & Color: 7/10 — Warm fire portal pops well. The large orange and red fire portal creates strong warm contrast against the cool stone cave background, giving the image a natural focal glow. The main character in the center benefits from good rim lighting against the dark cave walls. In grayscale, the bright portal and lit character separate cleanly from the background, though the flanking smaller characters on the right edge blend into the darker stone at tiny size.
  • Uniqueness & Polish: 7/10 — Charming indie polish, not standout. The chibi character art style is polished and consistent with Core Keeper's established visual identity, and the dramatic fire portal arch creates a memorable staging. However the overall composition of a character standing before a glowing portal is a common trope in indie RPG capsules and does not immediately communicate a distinctive selling point. Compared to top-tier benchmarks it reads as competent indie rather than genre-defining.
  • Brand Consistency: 8/10 — Cohesive with established art style. The chibi character design, warm underground cave palette, stone textures, and glowing elemental effects are all strongly consistent with Core Keeper's known visual identity from screenshots and prior capsules. The logo treatment with its signature font and color scheme reinforces brand recognition. The Void and Voltage subtitle ties directly to DLC theming and the electric and void visual vocabulary expected from that expansion.
  • Composition: 7/10 — Clear focal point, minor edge issues. The central character positioned in the archway with the fire portal as a framing device creates a strong natural hierarchy with one dominant focal point. The logo sits in the lower-left in a workable position that avoids direct conflict with the main subject. At small size the composition holds reasonably well, but the secondary characters on the right edge are close to being cropped and feel slightly imbalanced, adding clutter without contributing meaningfully to the read.

What works

  • Strong warm portal contrast. The large orange fire portal creates immediate eye-catching warmth against the cool cave background, ensuring the image pops on Steam's dark #1b2838 interface.
  • Polished chibi character art. The main character is rendered with clear silhouette, expressive design, and good rim lighting that makes them readable even at small sizes.
  • Effective cave archway framing. The stone archway naturally frames the character and portal, creating depth and a built-in focal hierarchy that works across sizes.
  • Strong brand identity recognition. The consistent art style, character design, and logo treatment align tightly with Core Keeper's established visual brand.

What hurts the capsule

  • Subtitle unreadable at small sizes. Void and Voltage subtitle text is too small and low-contrast to be legible at 231x87 or smaller, wasting the DLC branding opportunity.
  • Right-side characters add clutter. The smaller secondary characters near the right edge blend into the stone texture and add visual noise without reinforcing genre or story at tiny size.
  • Generic portal composition trope. Character standing before a glowing portal is a very common indie RPG capsule convention that reduces uniqueness relative to top genre benchmarks.
  • Mining sandbox not immediately communicated. Despite Core Keeper being defined by its mining and crafting loop, nothing in the capsule explicitly signals those mechanics, potentially confusing new viewers.

Priority fixes

  1. [title_readability] Increase the size and contrast of the Void and Voltage subtitle text so it remains legible at 231x87, or integrate it into the logo as a stronger lockup.
  2. [uniqueness_polish] Add a subtle visual cue referencing the mining or crafting identity, such as a pickaxe, ore vein, or resource element, to differentiate from generic action-adventure capsules.
  3. [composition] Reduce or reposition the secondary right-edge characters to eliminate edge clutter and improve balance so the main character reads as the sole focal point at tiny size.
  4. [genre_clarity] Incorporate a small but recognizable crafting or underground exploration cue into the composition to immediately signal the sandbox mining RPG genre to new viewers.

Store copy priority fixes

  1. [uniqueness] Rewrite 'DISCOVER AN ANCIENT WORLD' or add a new section that explicitly positions the Cavelings encounter, legendary Titans mechanic, and playable instruments as signature features unavailable in comparable games.
  2. [feature_communication] Clarify the progression system in one place—specify how leveling, talent points, and skill mastery connect to combat power, tool effectiveness, or new gameplay options, rather than repeating the phrase without context.
  3. [feature_communication] Add a sentence under BUILD, CRAFT & GET CREATIVE explaining whether base building is purely cosmetic or unlocks functional benefits (storage, automation, NPC interactions).
  4. [hook_strength] Strengthen the opening of the detailed description by replacing the generic 'Awaken as an explorer' with a question or tension hook tied to the Core mystery introduced in the short description.
