Twistris

Twistris is a browser-based falling-block puzzle game inspired by Tetris. Tetrominoes fall from the top, but instead of clearing lines they attach to a central mass that can rotate by one 90 degree step when the structure becomes imbalanced.

The goal is to grow the largest centered square. There are no line clears.

Each time the centered square expands by one layer, the player earns a Pulse charge. These charges are intended to become a spendable currency for future repair and board-shaping mechanics.
