Performance things - deviates from the GameObject base class quite a bit:

• [ ] Enemies should all shares the same texture, no reason for them each to load a texture from a file when they instantiated. Pass in std::shared_ptrto single texture thatEnemyHandler` can own.
• [ ] Particles as well.

Should do this by overloading the constructor, that way can still give new texture if needed.
