Update 0.1.0

Hello fellow Dungeon delvers! I hope you guys have enjoyed the little mechanic demonstration from the first little demo! I have some new features to the demo and hope this gets people excited for The Neon Dungeon!

Features added:

- New test Enemy type, Un-defeat-able turret: it fires at a faster rate then other enemies and it cannot be destroyed.

- Game over screen: when you run out of health the game ends and you are prompted to try again.

- Money: currently it functions as a score.

- added a white cube inside the walls to test transparency

Bugs:

- none that I'm aware of yet (as of the current state of the game)
