The player guides a green blob down a square tunnel using the arrow keys. The player can move forwards, backwards, or to either side, and may move from one wall to another by moving laterally, bouncing off of a pink panel or going through a green panel. Whatever wall the blob is on appears as the floor to the player. The player can only walk or land on given tiles. Bouncing onto a red panel results in death. A hole can be turned into a tile by rolling a ball of residue into it.

Previews
Flue was first hinted at on the May 9 Friday update post in 2014, where Nitrome presented the possibility of releasing a new game the following week.[1] A screenshot of the game was officially announced on May 13, 2014. The post showed a GIF of the gameplay and also revealed that it was an icon game.[2]

Trivia
The level select screen icon for level 15 is a skull instead of the number 15.
For the Nitrome Jam game Loop, there is an icon for Flue in the "More projects created by this team members" section.
The icon
In the game's logo, the letter E in "Flue" is backwards.
The title of the game could be a play on words, as "flue" is a homophone for the common nickname for the influenza virus.
