Echochrome (a timeless puzzle game)
I say timeless because it came out a few years ago but, like Little Big Planet, the style is timeless so it won't feel like you're playing a dated game.
I searched for a thread before making this one but the one I found was from before the game was even released (and half the thread went off on some tangent) so I thought I new one might be more appropriate.
Anyway, I had enjoyed playing this on a friend's PS3 a few years ago and was thinking about it last night so I decided to purchase it from the PS Store and it's every bit as enjoyable as I recall.
It's a very basic puzzle game about shifting perspective so if you're looking for action you may want to look elsewhere. But if you're looking for a good, thought provoking puzzler, look no further.
Like Little Big Planet, most of Echochrome's levels are user created but accessing the levels is very straightforward and simple.
Also like Little Big Planet, those that are so inclined are given the tools to create their own levels.
I'll end this posting with a clip of the game to give you an idea. I just thought the puzzle minded people of Little Big Planet might appreciate and enjoy Echochrome as well.
