I have added a redundancy to the screen resolution script, so hopefully it will not try to open the game in an impossible window size - thereby defaulting to a size too small to actually play. This will not give any error messages, but if an impossible window size is attempted, it will default to 1280 x 720.
A player discovered a problem when running out of oxygen. Somehow it caused his health to increase, and thereby increased his movement speed to absurd levels. This should now be resolved, but let me know if you encounter any related (or unrelated) issues.
