Hard-as-nails pixel-art game League of Evil has just been updated, turning Ravenous Games's old skool platformer into a Universal app for iPhone and iPad.

In League of Evil, you take on a cabal of villainous scientists across more than 160 challenging levels by jumping, flipping, and jumping some more.

It’s a pure retro romp with tight and responsive touchscreen controls, and was the recipient of a Pocket Gamer Bronze Award on review in February.

League of Evil is available now from Apple's App Store for 69p / 99c.

And if you manage to somehow complete the League of Evil experience, feel free to tackle these other top toughies on iPhone.
