Designing some levels

Remember our sprite sheet that we introduced in Chapter 12, Abstraction and Code Management - Making Better Use of OOP. Here it is again, annotated with numbers that represent each tile that we will build our levels from:

I placed the screenshot on a gray background so you could see clearly the different details of the sprite sheet. The checkered background represents the level of transparency. So, all of the tiles except for number 1 will reveal at least a little of the background behind them:
