Trevor Bradley updated his “Factor – A Game of Primes”.

Release notes:

I’ve finally polished Factor to where I want it. All new graphics, crash bugs gone (I hope!) saved high scores and an upgrade to Ultimate Fenix. If you enjoyed previous versions of Factor, hopefully this version is a bit more shiny. :
