ACK: Return Protocol is a fast, tactical puzzle game about building a safe signal route under pressure.
Guide the packet through a shifting network, steer around firewalls and interference fields, secure the target, then bring the ACK safely back to the core.
Every run demands quick decisions and clean path planning:
• Swipe to queue turns and redirect your route
• Avoid blockers, scan zones, and changing network hazards
• Secure relays before the transmission window closes
• Retrace the route to complete the return protocol
• Chase higher scores and unlock achievements
The network changes. Keep the signal alive.
Route the signal, outsmart hazards, and return the ACK before time runs out.
