Burnie the Fire Elemental must survive waves of attacking demons while preventing the Bat-Like Mailer Daemons from escaping to deliver a message.

Each time a Mailer Daemon gets past him, the time limit is suspended, and he must battle a gigantic multi-tentacled, shape-changing demon called the Zuuling.

Move Burnie using the keyboard, and fire by aiming the mouse. The longer you hold the mouse button, the larger the fireballs Burnie can hurl. Large fireballs are faster and can burn through multiple demons.

Shooting fireballs uses Mana, which can be replaced by holding the spacebar to Meditate. Meditation leaves Burnie vulnerable. Demons drop mana powerups when you send one fireball through multiple demons, each one leaves a larger powerup. Demons also drop life powerups when you create chain-reactions by burning demons that touch each other.

The game is actually episode 112 of the webcomic Nerdcore: the Core Wars. There are three possible endings, depending on how well you perform. The game has 3 difficulty modes, 3 speed settings, and Audio options.
