Whatever you do — don't press ALT and F4. No body. No memory. Just two keys: ALT and F4. You are a virus — and this PC is your hunting ground. Burrow into the system, devour programs, and corrupt everything in your path. Rule this digital world. Or be deleted trying.

About this game
Conquer the System! You are a highly intelligent virus born to infiltrate and conquer an aging computer system. Evade the strict surveillance of Antivirus programs and hack your way to the core in this unique 2D sequence-puzzle game!
Key Features:
Unique 3-Action Turn System Plan your moves carefully! Every three actions you take constitute a single turn. Calculate your movement, tile interactions, and command inputs to create the optimal execution sequence within your limited turn.
Hack with Real Keyboard Shortcuts Go beyond simple movements by utilizing abilities inspired by actual PC shortcuts. Use commands like ALT + TAB to seamlessly teleport between active windows and evade Antivirus tracking, or combine them with ALT + F4 to unleash powerful system-altering effects.
Outsmart the Antivirus The system is actively trying to purge you. When your intrusion is detected, Antivirus programs will deploy to hunt you down. Skillfully dodge their pursuit, or manipulate and toggle the floor tiles to destroy them completely.
Evolving Puzzle Logic The deeper you infiltrate, the more complex the system becomes. Discover new interactive tiles as you progress. Unlocking new chapters grants you access to entirely new shortcut commands, drastically shifting the puzzle logic and keeping the challenges fresh.
60 Stages of System Conquest Test your logic across 4 distinct chapters containing a total of 60 challenging stages. Can you reach the deepest parts of the system?
Minimalist Retro Pixel Art Dive into a nostalgic cyber-world. The game features striking retro pixel art with a strict monochromatic black-and-white base, accented by only one or two RGB colors. This minimalist aesthetic perfectly captures the cold, mechanical vibe of an old operating system.
