When Echochrome was first announced at E3 a couple years back, it blew my mind. The notion of using perspective to essentially "correct" reality was so rife with possibilities that I couldn't wait for the game to finally hit. The end product, creative as it was, ultimately didn't quite live up to all those possibilities -- even with a built-in editor that allowed users to create their own puzzles. Part of the issue was the laser-like precision needed to make the perspective-based puzzles work; leave just a tiny fraction of a walkway exposed and the illusion wouldn't "work."
This was exacerbated on the PSP where the amount of precision needed didn't really lend itself to the portable's particular analog... quirkiness. Some limited snap-to options helped, but in the end Echochrome never seemed to gel into an experience that matched that initial reveal. The staid string instruments and clompy footsteps were a neat concept, but in actually playing things, it all seemed to lose its magic.
