Arithmetic Meets Aliens:

In Far-Out Finley, you control Finley, or his brother Twinley,  as they search for number tiles on their space station grid- all while collecting power-ups, dodging increasingly unpredictable meteors (bad), battling a wizard (also bad), and avoiding the infinite void (really bad). You have full control over which multiples to find and are free to customize the game to your skill level.
