Quabricks

Quabricks is a modern falling-block puzzle game built with SDL2.

It implements the familiar guideline-style rules (ghost piece, soft drop,
lock delay, hold, 7-bag randomizer, wall kicks, T-spin scoring) with a
modern look: pastel beveled blocks, a clean HUD, and escalating sound cues.

Two modes are included: Marathon (level up and chase a high score) and
Time Attack (start with 60 seconds and earn more time by clearing lines).
