Frets on Fire 1.3.110

Frets on Fire (abbreviated 'FoF') is a free, open-source Finnish music video game created by Unreal Voodoo. Players use the keyboard to play along with markers which appear on screen, with the aim to score points, achieve a high point multiplier, and complete a song. Frets on Fire was the winner of the Assembly 2006 game development competition.
The game is written in the Python programming language, and is licensed under the GNU General Public License, although the game incorporates other free and open-source code under other licenses. The game's included song files and some internal fonts are proprietary, and their redistribution is not permitted outside of the Frets On Fire executable.

Frets on Fire is a video game that imitates the commercial game Guitar Hero. It is playable on Windows, Linux and Mac OS X. The player presses buttons in time to coloured markers, which appear on-screen, the markers are matched with the rhythm of the music. Frets on Fire can be played by using a keyboard by pressing the fret buttons and pick buttons, although there is support for joysticks, meaning that with the appropriate adapter and/or software, various guitar-type controllers can be used as well.
Colored, square-shaped markers appear on the player's screen, synchronized with the song, and are played by holding the fret buttons that correspond with the correct color, and pressing one of the pick buttons, at the correct moment. Every ten correct hits increase the score multiplier, which multiplies the points for every hit by up to four times. The multiplier is reset when the player misses a note or strums at the wrong time.
