Sandbox Progression Kit

Sandbox Progression Kit is a set of 11 progression and reward components drawn in the voxel style, where each surface is the front face of a cube with a lit top face and a shaded right face. It contains four skill tree node states, empty, half and full rating stars, a level badge, an experience ring and an ability cooldown ring.

Progression screens are where state matters most and where colour is least reliable: a skill tree is already covered in ability art in every hue, so a node whose state is only a border colour is unreadable the moment it has an icon in it.

The extrusion is real geometry rather than a shadow: the light angle never changes, there are exactly three tones per block, and the front face is inset so the cube stays inside its own sprite bounds.

Inside that style this is the Sandbox reading of it: a light interface on a desert tan palette with sky blue accents, built around a header band across the top of the frame, chamfered buttons at 112x40, banded bars divided into 12 segments, and two-tone icons on a 16px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

The locked node is hatched, the maxed node carries four corner ticks, and the available node is simply the plain face — three states told by texture and count rather than by hue. The two rings share one geometry and differ only in fill direction and colour, so they line up when stacked.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Sandbox family, which means this kit and the Sandbox panel kit line up without either being resized. A good fit for voxel and blocky games.
