beta #4

For this new beta a few things were added.  First of all, I made the moving platforms come closer to each other since the gap made it really hard to time your jump perfectly. the main thing I added here is the new enemy: Shawty Mc Shoot. As you can guess, it's the same enemy as the basic one, but it shoots. Most of the time spent on making this enemy work was spent on debugging a couple of bugs, mainly the fact that when the player would get killed by a bullet, it would crash the game. This was due to the fact that when the player died, it's SetActive was simply set to false, to fix that, I replaced the SetActive with a component remover to remove  the sprite renderer and also a new bool which determines if the player can move.
