So what did i implement in my engine?

• Background is working and can be animated.
• Text class is made more simple to use.
• New Sound class for making sounds and playing them.
• Reworked the Space Invader example: moving background, score, sound for shooting.

It’s a fair amount of work, but I’m not too happy because i had to think about how to implement some stuff and i think i wasted some time overthinking these problems.
