v0.5

This is relatively bigger than the other... after a month break.

•  Added Parallax Background
• Fixed collision layers on most objects
• Added Sniper Enemy then fixed it after being bugged in the test version
• Redone Standard Enemy (Chase)
• Added random Position function for Player, Exit point, and enemies. (So that every run is different)
• Redone Sniper Again cuz it's very buggy!! Fixed for now.
• Added HUD for player
• Added exit button on menu (IDK if it works in web tho)
