[FEATURE] Life moons

[maxogod]

🚀 Feature

Extra lives (consumable item)

Motivation

As the game progresses players will have a chance to randomly get a life moon to regenerate a lost life.

Implementation

• The life moons will occasionally spawn and move down in a straight line (it should be random but strictly after a given timeout after the last life moon).
• They will regenerate a lost life or add more on top of the 3 starting lives. although a player will have a max of 5 lives.
• There will be at least 1 of these guaranteed at the start of the boss fight and at the end.

Additional context

The probability of spawn - TBD.
