Attack of the Primes

As robots bent on world-factorisation plummet from the sky, you must destroy as many as you can!

Hit the numbered robots with their prime factors to overpower them. But be warned, they are coming in faster and faster, so you may struggle to keep up. There are three levels of difficulty, the hardest presenting the highest artillery of prime factors for you. Good luck!

Attack of the Primes is a remake of my old game Primesmash, using a different engine, lots of bug fixes and difficulty levels, and graphics that aren't squares! (mostly...)
