You defend a living motherboard from malware packets racing copper traces. Component towers (resistor, capacitor, diode, fuse) exploit circuit rules; jumpers let you reroute the board between waves. Signature: pull a fuse to deaden a whole trace.
Dark PCB green board, bright copper traces, solder-joint glints, blinking LEDs, neon scanlines.
Click, Enter or Space to start. Place and upgrade towers with the mouse and number keys, or by tapping on touch, to stop each enemy wave before it reaches your goal. The HUD tracks lives, cash and wave.
