Added Enemies and Projectiles

Blueprint UE: https://blueprintue.com/blueprint/1brafrht/

I added cubes that can be collected and thrown by the player. Above is the code for it.

Additionally, If thrown outside of the play area, they return to their spawn location.

Enemies were also added to the game. Upon collision with the player, the enemy is killed and the player's health is reduced. Being hit by a cube also kills enemies without harming the player. If all enemies are killed, a random amount of them will spawn back in.

If the player's health is reduced to 0, they'll be respawned at their last checkpoint.

If the player collides with a "Potion" their health will increase by 15. The potion will eventually respawn at a random location.
