About Ikemen GO

Ikemen GO is a fighting game engine for creating and playing 2D fighting games. Its homepage says it supports M.U.G.E.N resources, so existing M.U.G.E.N content can be used with it. Creators can script game modes and story paths in Lua and program characters in the ZSS scripting language. The engine supports online two-player versus matches using rollback and delay-based netcode, as well as cooperative arcade and survival modes.

The homepage states that the engine runs natively on Windows, macOS, and Linux, and that it has been in development by a group of contributors on GitHub. It lists stable and nightly builds for download, with older builds available through a separate link. The homepage describes the source code as available under the MIT license, which it says permits personal and commercial use at no cost. The directory entry lists the project as not open source, so the licensing status should be checked against the project's repository before relying on it.
