 This is not required to complete the game, but may bring similar bugs in
 other games.

 TESTCASE:
 1. Start Alpha Polaris
 2. Begin first day, click through intro until you gain control over
 character
 3. Press Ctrl+F3 result

 EXPECTED RESULT: Game secret combination is used to cycle through various
 shadow types

 ACTUAL RESULT:
