About NES Virus Cleaner

Platform: NES
Developer: Robert L. Bryant (Sly Dog Studios)
Year: 2011
Genre: Action
Players: 1
License: Homebrew

A maze game set inside the NES: Sly Dog Studios' robot Clik cleans viruses out of 17 sectors of the console.

You go from the controller ports to the APU, the PPU and the CPU, each a circuit-board arena with sparks and other enemies, and each with a briefing screen. Viruses appear one at a time; each is worth 50 points and extra time, while a hit costs 100 points and a life. You can place a teleporter anywhere and warp back to it, but each warp costs 1,000 points. Clik introduces himself at start-up and explains the rules.

Robert L. Bryant of Sly Dog Studios released it quietly at the end of May 2011 as a download and a cartridge, which sold out. RGCD gave it 3 out of 5, calling it a charming, challenging arcade-puzzle hybrid while criticising the steep score penalties and the price of the teleporter; it praised the cartridge label art.

How to play

Controls: A places a teleporter and A again warps to it, for 1,000 points per warp. B removes it.
