Pixeltris

Pixeltris is a falling-block game with a picture at the bottom of the well. Clear a line and the picture grows. The opening card shows exactly that: a four-block piece turning into a heap of coloured pixels.

The controls are printed down the left edge and stay there while you play: arrow keys or A and D to move, up or W or X to rotate, down or S to soft drop, space to hard drop, P to pause, R to restart.

The same panel shows the score, line count, level, a running clock and a percentage bar. That bar tracks the picture. A handful of hard drops cleared five lines, and it jumped from seventeen percent to fifty-two.

Everything else is stripped back: a plain purple backdrop, a black well outlined in white, a next-piece box on the right, and a colourblind switch on the opening card for anyone who needs it.
