New Revulsion patch is up, bigger announcement with more information soon.

This patch invalidates previous save game files. This is the last time this will happen baring some unforeseen feature creep. (Very unlikely)

It may be a good idea to delete your old save game slots

C:\Users[username]\AppData\Local\ProjectStray\Saved\SaveGames
And delete the save slot files.

Sorry for the trouble on this one. But this patch changes the game a lot! I will release a formal update here soon to talk more about all of the changes to the game.
