Snake will only move if the cell is empty
Removed colliders from Frame and Body prefabs as they are no longer needed
When game ends by losing the snake flashes
Added background image creator
Removed 1 row for game HUD
Implemented swipe controls but may need tweaking to be more sensitive
Game has issues with the scaling which needs research
