SFG 0.1.5 update

Today i finally updated the game, now to version 0.1.5!!

I added a new game mode "Survival" wich is the third mode in the game. Survival mode has three difficulties: easy, normal and hard

Also this update fixed some bugs, the game still does not have backgrounds and some sprites but i will add some sprites eventually

PS: i am working on campaign
