BLACKWALL — Firewall Defense

BLACKWALL is a one-thumb firewall defense game: you are the sentinel AI guarding a server core. Trusted traffic wears a smooth cyan hex frame — let it through to score and charge your UPLINK. Hostile payloads wear a jagged, rotating red frame — tap them to BLOCK before they breach. Build a chain multiplier, deploy the charged PATCH ability to purge the screen, and survive escalating waves of viruses, worms, trojans, phishing, ransomware and DDoS. Ships an educational threat codex and a global best-score rank.
