I just downloaded the demo of Echochrome on the new Playstation Store. It’s pretty awesome, and I’ll probably buy the full version when it comes out. It’s very cool, using cool perspective tricks to solve puzzles. There are 5 laws of perspective (these can all be seen at the beginning of the trailer, below):
Using those 5 laws, you rotate the camera angle to guide the avatar from ‘echo’ to ‘echo’. These ‘echos’ serve as checkpoints, in case you fall through a hole or jump into nothing. It’s pretty easy to get the hang of, but I find that the camera doesn’t rotate fast enough, and the motion sensor mode is too jumpy to be useful. Hopefully that will be fixed up by the final release, but I really like the demo. Check out the trailer below:
