click start, then which level you want to play (after clicking the green flag). click to fire at your mouse pointer. This game is infinite. ----- UPDATE: 5/31/2023: Level 2 now gives you double the points, and enemies spawn and fall faster.
Idea for progress bar from @juswitzky-aes Progress bar made with Google Drawings (drawings.google.com) Idea for different explosion from @jost3abc If your computer is slow, some objects cannot be destroyed these objects will sometimes give you huge score boosts.
