Quick text summary

Portal 2 scored 72/100 on Steam Analyser — Good for a Steam capsule. Top priority fix: [contrast_color] Add a subtle dark vignette or deep background gradient behind the tile grid so the capsule reads cleanly against Steam's dark #1b2838 background without losing the sterile aesthetic.

Priority fixes

  1. [contrast_color] Add a subtle dark vignette or deep background gradient behind the tile grid so the capsule reads cleanly against Steam's dark #1b2838 background without losing the sterile aesthetic.
  2. [genre_clarity] Scale up or reposition the cyan stick figure so it remains visible and readable at tiny thumbnail size, reinforcing the portal-traversal mechanic for first-time viewers.
  3. [composition] Pull the stick figure slightly inward from the right edge to ensure it survives Steam cropping across all capsule display sizes.
  4. [uniqueness_polish] Consider adding a subtle orange portal glow or secondary portal element opposite the blue figure to reinforce the dual-portal mechanic and add visual dynamism without cluttering the design.

Store copy priority fixes

  1. [hook_strength] Rewrite the short description to lead with core gameplay: 'Solve increasingly devious first-person puzzles alone or cooperatively using gravity-defying portal mechanics, supported by a witty AI and original soundtrack.' This prioritizes the game's actual appeal over the editor feature.
  2. [uniqueness] Add a concrete differentiator in the opening detailed description paragraph, such as 'Portal 2 expands the original's portal mechanics with gravity wells, laser redirection, and destructible environments, creating puzzles that demand cooperation, not just coordination.'
  3. [feature_communication] Replace vague feature items ('Original music,' 'Massive sequel') with concrete descriptions: 'Original score by the composers of Half-Life 2' and 'Twice the single-player campaign, fully separate co-op story with new mechanics.'
  4. [audience_targeting] Clarify in the short description or opening sentence whether this game is primarily for solo puzzle enthusiasts, co-op pairs, or both, to set expectations early.
