PSP game review: "Echochrome" (2008)

The gist: Manoeuvre what looks like an artist's dummy around monochromatic 3D structures by altering the perspective to suit. For example, if there's a gap in the path blocking your way, rotate the screen so it's hidden behind a pillar. Your character will now keep walking as if it wasn't there!

Selling points: Enough puzzles to last a nuclear winter. After the simple tutorial and early levels, things become increasingly head-scratching as you're confronted with multiple staircases, manholes, trampolines and dudes to control. There's also a classical score with vocals and strings. Even if you solve everything, you can go back and try to beat your best times – or create your own landscapes and share 'em with mates.

It's kinda like: Being trapped inside an MC Escher drawing. Oh yeah, and the "Walker" reminds me of the little men from the ancient "Lode Runner" series of games. They got bloody hard, too.

Final word: Shades of genius.
