Issues unresolved[edit]

Toggle fullscreen key doesn't work in-game[edit]

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[edit]

Steam achievements not unlocking[edit]

Disadvantage 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.

Steam achievements on OS X[edit]

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[edit]

  • Does not appear to be a fix for this yet. Also happens when pressing Windows key.

Solution: press F, it toggles fullscreen.

Steam Community does not work in full screen[edit]

  • If you are playing the game in full screen, you will be unable to access Steam Community's Shift Tab overlay.
