"Free as in Freedom, Free as in Priceless"

Welcome to the home page of Piga Software: we are a cooperative of programmers developing free software for GNU/Linux and occasionally other systems, with a particular emphasis on game development. Our software is released under the GNU General Public License version 3, though some individual files within projects might be under other copyleft licenses and are listed in project copyright disclaimers. Some content from our games by MWM may also be available under the GFDL and CC BY-SA on their wiki database.

Although we have used Visual Basic 6, QBasic, Game Maker and even ZZT-oop, most current projects are built in Gambas - a free software BASIC-style OOP programming language consisting of an integrated development environment and run-time inspired by Visual Basic and Java that is well suited to rapid application development. Our particular areas of interest are strategy, adventure and platformers, first-person games and interactive narrative, often with a sense of humour; though we work on whatever suits us at the time, and some projects are developed for a specific use case, as well as general use applications.

More details on who we are and what we do can be found at PigaLore, the Piga Software Wiki; we are also active on the Gambas ONE and FreeGameDev forums.

    • Sprite Stage handles sprite-based layered cell animation.
    • Cutout Coliseum is for segmented cutout animation.
    • Speech Generator allows the production of speech files for automated lip flaps, subtitling and text-to-speech.
    • Character Creator will allow for the defining of digital puppets with model sheets and defined traits.
