Free Desktop Flash Player, free from many flaws of Ruffle emulator used by most sites hosting the webgame version. Also again it's free unlike the trilogy on Steam.

How to use:

1. Install the Newgrounds Flash Player
2. Find the game on newgrounds.com (https://www.newgrounds.com/portal/view/661412)
3. Press "Launch In Newgrounds Player"
4. Play the game like it used to be before Flash went down (except clicking on ads is safe and the game doesn't pause when out of focus)
