A downloadable game for Windows

Made for the Ludum Dare 38 compo, 48 hour game challenge.

Your system is being invaded by tiny computer parts! Repel the invaders!

Use WASD to move and tab to switch move scheme between relative to the mouse and relative to the screen!

Click to shoot the enemies, getting hit will cause you to take damage! Don't let them take your system!

When you get to the boss fight don't panic! The HDD will repel your bullets but don't fear! Run up to the red USB port on its front and plug in!


When hacking you must bypass the enemy's security by turning all the bits to one using bitwise operations!

Select the operation that you want to use at the top and drag the bit packets onto the enemy's to apply the operation!


1 AND 1 = 1, 1 AND 0 = 0, 0 AND 0 = 0

1 OR 1 = 1, 1 OR 0 = 1, 0 OR 0 = 0

1 XOR 1 = 0, 1 XOR 0 = 1, 0 XOR 0 = 0

Defend your system and repel the computer parts!
