Update 1.1

Added a new map, a difficulty system, a brand new tower and new waves.

Fixed a bug where the enemies wouldn't get hit sometimes.

Fixed a bug where the waves wouldn't advance even after killing all enemies.

I decided that I'll be making this tower defense game more of like a series of games. This one is still very basic so I'll use it as kind of a prototype to learn and to make better projects in the future.

Hope you guys enjoy!
