1.0.8? and what about updates since 1.0.3?
There have been small updates of the game to fix some bugs or to add some effects. I have not considered it necessary to make a post about each of them.

As a summary, this is what has changed from 1.0.3 to 1.0.8:

• Added feedback from enemies when you hit them.
  
• Fixed a bug that caused bonus missions, on max difficulty, to not be assigned correctly.
  
• Fixed a bug that caused the fire of the rocks of the stone boss to make a strange trajectory when destroyed (it's only a visual error, it didn't affect the player at all).
  
• Fixed a problem that caused the player movement to be only in 8 directions (now the player has a better control over the submarine).
  
• Fixed other small bugs.
