A packaged desktop version is working and playable on Windows (tested on 8.1). Meaning I can release the game as an .exe which you can run at any time, such as offline.
In addition to running on Windows, support for Mac and Linux is 100% possible and doable within the same time-frame as when the Windows version is released. So expect to see all 3 version available at around the same time.
The packaged desktop version shall be released after some larger updates to Synth Invasion have been pushed. When the game is more fleshed out and feature-filled. No ETA on that.
