 is a badged game on Kongregate. It was developed by Mazapan and the music was created by Henrik Nåmark.

Gameplay
There's a boss at the end of the tunnel the player starts in. However, he can't be hit by the player's weapon (that is activated, conveniently, by almost every key on the keyboard). In order to defeat him, you have to burn the rope. Touch a flame on the wall to get flame on a stick, with which you burn the rope. Falling from too high, getting hit, or throwing your weapon, will result in the loss of the fire. The player is immortal.
