Issues unresolved
Toggle fullscreen key doesn't work in-game
On the options menu, it states F is the key you use to toggle fullscreen/windowed mode. However, this only works on the title menu or in the pause menu. In-game, pressing F does absolutely nothing unless the game is paused. Currently, there is no fix for this.
Issues fixed
Steam achievements not unlocking
- On certain systems Steam achievements may fail to unlock and get registered.
A fan made fix has been developed to solve this issue on Windows.[2]
Steam achievements on OS X
For the achievements gained on OS X to be unlocked in Steam, one has to copy and replace the so.sol files as outlined here. The file is located in:
~/Library/Preferences/Macromedia/Flash Player/#SharedObjects/''<Random String>''/localhost/
After extracting it, follow the instructions given in the aforementioned link. Finally launch the game and see the achievements unlock.
Alt+Tab Crashing
- Does not appear to be a fix for this yet. Also happens when pressing Windows key.
Solution: press F, it toggles fullscreen.
- If you are playing the game in full screen, you will be unable to access Steam Community's Shift Tab overlay.
OS X Retina Display Slowdown on Mavericks+
- Scaling on Retina displays appears to cause a slowdown between loading screens and during complex scenes.
Set Open in Low Resolution[3]

- Go to the installation folder.
