I want an earlier version so I can play at an earlier part in the game? I downloaded the latest one and I could only play through the beach segment, after which, it told me the game was still in development.
This version has the full game; however, changes made in this version broke older saves. When you started the game, you should have had the option to either start with the new content in this version, or at the beginning.
If you have saves from an older version and want to continue up until the end of the 0.9.9 content, then yes, an old version might let you do that. However, if you intend to continue to play the game, you
might be better off biting the bullet and replaying. To access anything earlier, you would have to do that eventually. Indications seem to be that there will be some sort of new content added eventually (a more specific evil karma path).
Replaying now, however, runs the risk of further code changes forcing yet another restart.
Note: if this is the first version you've played, then you should be able to try to start again, and choose the option to start from the very beginning.
