Jump over puddles of lava by pressing SPACE or UP ARROW.
My first attempt at making a platformer, which I understand to be a Geometry Dash-like game. The cat tries not to step into lava by jumping over the lava puddles. If the cat steps into lava, the game is over. The implementation uses two sprites: 1. The Cat. This sprite's job is to change costume back and forth to give the impression of the cat running. 2. The Line. This is a much more interesting sprite because it clones itself to give the impression of the running line. In fact, each line sprite is a short line segment. Each clone moves left at constant speed. When a clone gets far enough left and it has not cloned itself yet, it creates another clone. This produces the desired effect.
