A heavy, geometric sans with squarish, superellipse-derived contours and consistently rounded corners. Strokes are thick and steady with clean, planar terminals, producing a solid, machined silhouette. Counters tend to be rectangular and tightly enclosed, and the overall spacing feels compact, reinforcing dense, punchy word shapes. The lowercase follows the same modular construction with simple, sturdy forms and short, squared-off joins, while numerals echo the same rounded-rectangle logic for a uniform texture across alphanumerics.

Best suited for short, high-impact text such as headlines, brand marks, product titles, and bold callouts. It can work well in tech, gaming, or industrial contexts, and in signage or packaging where a sturdy, modern presence is needed. For smaller text, generous sizing and spacing help preserve counter clarity.

The overall tone is assertive and utilitarian, with a distinctly digital, game-like energy. Its softened corners keep it from feeling harsh, but the dense construction still reads as powerful and mechanical—suited to bold, modern interfaces and sci‑fi flavored branding.

The font appears designed to deliver a strong, contemporary display voice built from rounded-rectangle geometry, emphasizing robustness, consistency, and a distinctly digital feel. Its softened corners and modular construction suggest an intent to balance toughness with approachability while maintaining a clear, iconic silhouette.

The design language is highly consistent across glyphs, favoring simplified geometry over calligraphic modulation. The compact counters and heavy weight suggest it will be most comfortable at display sizes where interior openings remain clear.
