S.E.M.I. – Side Effects May Include... scored 78/100 on Steam Analyzer — Good for a Co-op capsule. Top priority fix: [title_readability] Increase tagline font size or weight to ensure 'SIDE EFFECTS MAY INCLUDE...' remains readable at 120x45 thumbnail scale.

Capsule scores by dimension

  • Genre Clarity: 8/10 — Chaotic action platformer clearly read. The capsule immediately communicates a colorful, comedic action game through exaggerated character poses, bright particle effects, and dynamic composition. The cartoon-style characters in various states of chaos, combined with the whimsical lab setting with floating orbs and energy effects, strongly signal an indie action-comedy platformer. At tiny size, the vibrant color palette and character silhouettes remain distinctive enough to convey 'quirky action game' without confusion.
  • Title Readability: 7/10 — Clean title reads well at small. The title 'S.E.M.I.' uses a bold, geometric white font with strong letter-spacing that maintains clarity down to small sizes. The tagline 'SIDE EFFECTS MAY INCLUDE...' is rendered in a smaller, readable sans-serif below and remains legible at small capsule size. At tiny thumbnail size, the main title letter forms remain visible, though the tagline becomes harder to parse without causing the overall title to collapse.
  • Contrast & Color: 8/10 — Strong value separation against dark. The bright purple, orange, and yellow color palette creates excellent contrast against the Steam dark background (#1b2838), with character highlights and particle effects reading distinctly. The white title text pops cleanly from the colorful background, and the character silhouettes maintain clear edges even in grayscale due to warm-cool color separation. At tiny size, the composition retains visual punch due to high saturation and strong light-dark separation between foreground and mid-ground elements.
  • Uniqueness & Polish: 8/10 — Distinctive art style and premise. The capsule showcases a cohesive, polished art direction with custom 3D character designs, stylized patient models, and a vibrant lab environment that communicates the game's unique 'experimental drug chaos' premise. The particle effects, dynamic poses, and color grading feel intentional and premium rather than asset-flipped, differentiating it from generic action platformer templates. The visual storytelling—patients in various absurd states within a colorful clinic—immediately conveys the core mechanic of unpredictable side effects and co-op interference.
  • Brand Consistency: 8/10 — Consistent character design language. The capsule features a recognizable character style with proportional cartoony humanoids in distinct outfits and expressions, which maintains internal cohesion across the visible patient cast. The color palette—warm oranges, cool purples, bright yellows—forms a distinctive brand signature that appears consistent with indie action-comedy aesthetics. The lab environment, particle effects, and UI styling reinforce a unified visual identity that would be memorable and recognizable across store screenshots.
  • Composition: 8/10 — Well-balanced focal hierarchy. The composition places the four characters in a strong triangular arrangement with the center-right character slightly elevated as the primary focal point, while the title sits in a controlled lower-third zone with breathing room. Depth layering (background lab elements, mid-ground characters, foreground particles) creates clear separation and prevents clutter. At small and tiny sizes, the character cluster reads as a unified primary subject with the title anchoring the bottom, maintaining visual hierarchy without edge-hugging or awkward voids.

What works

  • Vibrant and distinctive color palette. The warm orange, cool purple, and bright yellow color scheme creates memorable brand identity and strong contrast against the Steam dark background.
  • Clear character-driven visual storytelling. The exaggerated poses and multiple patient characters immediately communicate the game's core premise of chaos and experimental effects without requiring text.
  • Polished 3D art direction. Custom character models, detailed lab environment, and refined particle effects convey premium quality and intentional craft rather than generic asset use.
  • Strong title placement and legibility. The bold white geometric font maintains readability from full header down to small capsule sizes with effective contrast.

What hurts the capsule

  • Tagline readability at tiny size. The 'SIDE EFFECTS MAY INCLUDE...' text becomes difficult to parse at thumbnail size, reducing secondary message impact during quick scrolls.
  • Character density potential crowding. At tiny size, the four-character arrangement risks visual compression, though current spacing avoids critical overlap.

Priority fixes

  1. [title_readability] Increase tagline font size or weight to ensure 'SIDE EFFECTS MAY INCLUDE...' remains readable at 120x45 thumbnail scale.
  2. [composition] Add subtle background gradient or vignette behind title area to guarantee text legibility regardless of character silhouette positions.

Store copy priority fixes

  1. [feature_communication] Replace 'imagination' with a concrete fifth ability or remove it entirely—vague filler weakens the clear ability list.
  2. [audience_targeting] Add 1–2 sentences clarifying solo campaign structure and whether single-player has separate content or is primarily a co-op game played alone.
  3. [feature_communication] Add a brief sentence explaining what puzzle-solving looks like in practice (e.g., 'use abilities to disable traps or create paths for teammates'), since it is mentioned in the short description but never detailed.
