Invert your colour to keep on climbing.

Some people call Simon a bit of a square but he has a real passion for reading, learning and most of all exploring. Help him as he explores the world of Invertical, collecting lots of fascinating books and scrolls along the way!

This platform game requires the player to invert their colour between black and white in order to land on the appropriate blocks. Get it wrong and you’ll go falling through the environment.

Invertical Touch

Previously a version of Invertical was released for iOS with a free version also available for Android and iOS. It is probably my favourite Oxygen Addict game.

Unfortunately this was released through a publisher and they have since pulled it (I think – I can’t find it anyway!) but the Lite versions are still available for free.
