What players say
Players enjoy this free tower defense game where you protect a CPU from malware, but they split on the difficulty: some find it balanced while others point to a steep spike after a boss fight. Many request a multiplayer mode, and a few note that tower stat information is hidden, making upgrades feel like an illusion of choice.
