Changed Look, Started Class layout

I created two Enemy classes
VEnemy, HEnemy
They are subclasses of Enemy
They start to show how we will want to build the rest of our enemies.
I added 1 VEnemy and 1 HEnemy to the screen. The HEnemy isn’t moving.
Maybe I’m missing something or maybe the clamp function is messed up.
Help?

Changed sprites. Moved HUD a bit.
