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
- Read the buffer, queued masks, and active operation.
- Plan rotations, flips, and token spends.
- Drop the piece—soft or hard—into the grid.
- Resolve XOR / AND / OR cascades.
- 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.
