Game development project created with Dark Flow, an application used for developing multi-platform video games; contains source code, project settings, and references to resources used by the project, which can include sprites, sounds, backgrounds, paths, and other objects.

A single Dark Flow project can be built for multiple platforms, including Microsoft Windows, the Web (as plugin-less Web games), and for console systems such as the Nintendo Wii, Sony PSP, and Microsoft Xbox.

Dark Flow follows DS Game Maker as Invisionsoft's next generation game development software. DS Game Maker is used for developing Nintendo DS games.

NOTE: Dark Flow is no longer developed.
