Auto-bombs Update

Hello everyone,

A few core mechanics have been changed to alter the gameplay.

- bombs automatically trigger when collecting more than 3 and when an enemy reaches the bottom. You can also still trigger them manually.
- Because of this automatic trigger, it will no more happen that more than one enemy can reach the bottom at a time. So the 10 life bar is removed, making the bombs also your extra lives.
- Lifes of a ship can now be 5, but it still starts at 3.

These changes are done so the game becomes more of a simplistic comfort game that you can control with just the D-pad. 
Making it easier to control with one hand on a phone too.
(Basically: No gen-AI is involved in making the bombs automatic.)

Hope you'll enjoy the game.
