Hotfix 0.3.4.5

Hotfix 0.3.4.5

- Added Debug Menu
Debug menu is here, Debug mode is almost completed. You can spawn singular enemies now, to test things out, or you can just play the waves. I know it works kinda bad right now, but i wanted to push that hotfix as soon as i can, so i will try to do something with it next patch

- Blocked Hard and Legendary mode again
It was kinda pointless to have those unlocked since they were impossible right now... Dont know why i unlocked them in the first place

- fixed not being able to lose
Somehow you just couldn't lose by losing base HP. Its fixed now, you are no longer invincible
