flies in a jar is a short retro horror puzzle game by Jet Simon, made for GitHub Game Off 2021. You are a security guard on your first night at a mysterious agency, watching CCTV cameras and decoding emails on an old computer to find out what is being kept there. Some puzzles need you to use your real web browser.
About flies in a jar
flies in a jar is a free browser game by Jet Simon, who made its art and code for GitHub Game Off 2021. The maker names Don't Feed the Monkeys as a big inspiration. It is set in 2007: you are a security guard at a mysterious agency called the FCL, and tonight is your first night on the job.
You never leave your desk. In the dark you have a keyboard, a mug, a keypad and a monitor with a green Securitech desktop, an email client and a light control program. Switching between camera feeds shows you a lit jar full of flies and other rooms that only open up as you go. The emails come in code, and solving them and the light controls unlocks more cameras and more of the story.
The tension builds slowly: grainy footage, low sounds, and the feeling of watching something you were not meant to see. Then the camera views start to show things that make players jump, a man in camera 2 most of all. A couple of puzzles ask you to use the real internet or your own computer to solve them; you never need a real phone.
The maker recommends playing with the sound on. The browser version is free; the English Windows download costs at least 1 Canadian dollar, and a free Spanish translation by Agustina Celestino is available. It suits players who like SCP-style secrets, ciphers and short found-footage scares.
