Bugfixes and improvements

This is just a small update with mostly bug fixes.

• Phoenix didn't spawn in boss rush mode
  
• Extra life didn't work in boss rush mode
  
• The secret-level boss wasn't a boss
  
• Next button in the glossary now works as expected when using a controller/steam deck
  
• Fixed translation errors
  

But I also improved some aspects of the game.

• Full screen mode will now be saved, and the game will be set to full screen automatically
  
• Exit game from main menu is now clearer
  
• Added new enemies
  
• Added time to local high score (last update)
  

Preparation for future updates

• Added crit damage as stat (base 100%)
  
• Added movement speed as stat (base 6)
  

Have a good weekend.
