On this page, you can download the game. Although I highly don't recommend playing the legacy version as
it isn't as good as the Remastered's demos or the full version, I recommend downloading either the full game
or try one of the demos. But if you want to try the legacy version, it's an entirely different game with an outdated
engine AND outdated broken code. If you want to try either the remastered's demos or full version, buy it and download.
If you really want a crappy version of this game, try out the legacy version.
