fracgame

fracgame is a clean-room Godot recreation of the 1990 DOS puzzle game FRAC. Solid 3D pieces fall into a 5×5×12 glass, completed horizontal layers disappear, and everything above them drops down.

The repository contains only the new implementation. The original DOS executable, artwork and other game files are not included.

Features

• Original nine solid piece types and their recovered selection weights.
• Keyboard and numeric-keypad movement, including diagonals.
• Single-button cyclic rotation.
• Active-piece projections on both far walls, without a floor shadow.
• Recovered DOS fall speeds, level timing, bonus table and scoring rules.
• Configurable glass dimensions, starting level, starting layers and available pieces.
• Local top-ten leaderboard.

Controls

• Arrow keys or QWE / AD / ZXC: move a piece.
• Numeric keypad 1–9: move in eight directions; 5 rotates.
• S: rotate.
• Space, Insert, Delete, keypad 0 or decimal point: hard drop.
• Enter: increase the speed level.
• P or Escape: pause.
