In this update, I have split up the second outdoor level into two parts, making them run smoother, and made a few minor changes to the outdoor areas. The basic flow of the game is unchanged. However, you will need to start a new game in order to play this latest version.
To try this latest version, go to "Paradox Vector > Properties > Betas" and select "beta" from the drop down menu. This will prompt the update. Let me know if you experience any trouble.
If you do not want to start a new game yet, keep playing the standard version.
