Virus Client is a 2D management game. Your goal is to keep your computer alive for as long as possible (you lose if PC integrity reaches 0%) and get as much money as possible, while also managing all the apps and malware that keep appearing in the PC. Each malware has different abilities that may help you or hinder you, so make sure to think about which ones you'll want to keep. Each app has different functions to help you manage, keep track of and learn about your malware, or just for fun.
There are also multiple other features and systems you can make use of to help you or just pass time. Read forums to learn about malware, read e-mails to GET malware, write notes in notepad, make use of the many tools in the drop-down menus, use apps to automate putting malwares in quarantine, etc. The game is also highly customizable. You change your wallpaper, your username and profile picture, and even background music.
Made for Major Jam #7: Wild, under the limitation "Unpredictable rules". (Side note: I suppose you could call this a spin-off of Bols, as it has the same artstyle, and the apps and malware are technically critters)
