Tomorrow will see the release of the demo for Catherine. The demo is set to look at the opening hour or so of the game.
Within the demo, the US PS Blog reports that:
Catherine is all about its story and characters; the fact that you’ll meet Vincent, his girlfriend, and his close circle of buddies in your short time with the demo should give you a great idea of what to expect in the full game. And then there are the nightmares… You’ll have to contend with a couple of those.
The game is all about puzzling, the protagonist Vincent is haunted by nightmares that manifest in the form of puzzles that he must complete or face certain death. The catch is that any death in the dream world kills you in the real world.
The game is out in the US on the 26th July.
