I can't say I remember PC and PS3 game Puzzle Dimension, but it seems like that 2010 spatial awareness puzzler was highly regarded. Now you can see for yourself, in the new iOS adaption Unpixelate.
The game is all about rolling a ball around these floating platforms to collect cubes and reach the exit.
Things start off simple, but the game soon toys with gravity, teleporters, and spikes in a campaign to frazzle your brain. You'll have rewire your cortex and adapt to this world's topsy-turny rules to finish all 100 stages.
Alas, from my brief trial with the game, I'll also say that the controls - a complex mix of taps, swipes, and pinches - will definitely take some getting used to.
But it's interesting and worthy of further investigation by puzzle game fanatics who are up for a challenge. If that sounds like you, give it a go - it's available now on iPhone and iPad for £2.29 / $2.99.
