Measured entry
8bitcn-duel-block
A client-side pixel-art duel card with alternating attacks, health state, winner and rematch flows, responsive fighter layouts, and default character art. It ships as a shadcn registry block plus retro CSS, and expects Next Image, React, path aliases, a cn helper, local Alert, Badge, Button, and HealthBar components, Radix Progress, utility styling, image assets, and a hosted font.

Verdict
A charming themed block, but not publish-ready from this registry payload. The build fails because the source imports an Alert primitive that the item neither ships nor declares. The bare failure also confirms it needs a shadcn-style setup. Avoid it unless you are willing to repair the registry wiring and own the surrounding 8bitcn stack.
Use it if
- You want a playful combat vignette for a game landing page or themed demo.
- Your app already uses the matching 8bitcn primitives and can supply fighter images.
- You are comfortable treating the attack logic as presentation rather than a game system.
Skip it if
- You need a registry item that installs and builds without repairing missing component dependencies.
- Your stack does not use Next Image, shadcn-style aliases, or utility classes.
- You need deterministic, configurable combat rules or externally controlled duel state.
- Your product cannot load the hosted retro font or provide the expected character artwork.
Install
| Declared dependencies | radix-ui, @radix-ui/react-progress, clsx, tailwind-merge |
|---|---|
| Missing on install | none |
| Bare install | fails once the shadcn-style helpers are removed, so it needs that setup |
| Provider | no provider required in the harness |
In a non-shadcn project, add equivalent path aliases and a cn helper, bring in or replace Alert, Badge, Button, and HealthBar, install Radix Progress, recreate the required utility styles and theme tokens, include the retro stylesheet and font policy, provide both fighter images, and use Next Image or adapt the image elements. The missing Alert must be added explicitly before the block can build.
