Fault Line by Nitrome
Fantastic platform puzzle game.
The basic premise is simple A-to-B level navigation. The twist is in the game mechanic, where you ‘fold’ the level at 2 key points. As you can see in the image above, there are those white markers which are the fold points, which rearrange the level to help you procede. Be warned - there are levels which you don’t have control of these, and care is needed!
