BITMASK

Purge a volatile memory buffer before it overflows.


Build: v1.0 Release
Engine: Godot 4.4
Platform: Web · Windows · Linux · macOS


Jack into the Core

Manipulate falling bitmasks, escalate the bus width from 4 to 8 bits, and stabilise the mainframe one purge at a time.

Key Pillars
  • Binary clarity keeps every bit state visible.
  • Fail-fast design rewards quick recovery.
  • Hands-on logic lets you feel each operation.
  • Keyboard-first flow keeps inputs frictionless.

Core Loop

  1. Read the buffer, queued masks, and active operation.
  2. Plan rotations, flips, and token spends.
  3. Drop the piece—soft or hard—into the grid.
  4. Resolve XOR / AND / OR cascades.
  5. Escalate bus width and pressure until overflow.

Bit Operations

  • XOR – Flip overlapping bits (default action).
  • AND – Carve away energised cells where both bits are 1.
  • OR – Fuse fresh 1s wherever the mask lands.
  • NOT – Invert everything (reserved for future corruption events).

Controls

  • Shift – Cycle operations (XOR → AND → OR)
  • Ctrl – Reroll current mask (once per drop)
  • ← / → – Slide mask
  • – Flip bit pattern
  • – Soft drop
  • Space – Hard drop

Objective

Flip every bit in a row to purge it from the memory buffer before overflow. Each purge accelerates the clock and expands the lane width from 4 to 8 bits—precision and foresight are everything.
