Measured entry

8bitcn-portal-transition

ctaskeuomorphism

A retro pixel-art call-to-action with a clickable portal, travel state, primary and secondary links, and configurable copy. It ships as a shadcn registry block for Next.js and React, importing Next Image and Link, a cn helper, local Badge and Button components, retro CSS with a Google font, and a portal image asset.

Verdict

A focused, characterful CTA for an established retro Next.js design system, but not publishable as a verified drop-in today. The tested build cannot resolve the base Badge component, and bare mounting also needs a shadcn-style setup with its utility alias and supporting primitives.

Use it if

  • You are building a game-themed Next.js landing page and want a playful portal CTA.
  • Your app already follows shadcn conventions and can supply the matching utility, controls, theme tokens, CSS, and image asset.
  • You want configurable destinations and an optional callback after the short travel state.

Skip it if

  • You need a framework-neutral React component without Next.js Image and Link dependencies.
  • Your project does not use shadcn-style aliases, utilities, and component primitives.
  • You need a verified drop-in build, because the registry item currently fails when its base Badge dependency is absent.
  • Your product cannot load the external retro font or provide the expected portal image.

Providerno provider required in the harness

In a non-shadcn project, add or replace the path aliases and cn helper, provide compatible Badge and Button components plus theme utilities, include the retro stylesheet and portal image, and adapt Next Image and Link if Next.js is not in use. Ensure the nested retro controls can resolve their base UI primitives.
