I thought it was a horrible game. Hotspots showed up in the wrong places, there were a couple of locations with extreme slowdowns, one of which required you to act quickly, and screen exits were often hard to find even with a walkthrough to tell you where to go. The squirming cursor was a real pain, though I've heard the patch improved it, or at least allowed you to turn the squirm off. For a 3rd person 2.5D point-and-clicker, it was awfully resource hungry - worse than some real time 3D games I've played. And on top of all the gameplay annoyances, the main character was a blank slate with no memory or personality to speak of. Throughout the game you never knew what she was thinking or feeling. You never had any idea whether she got her memory back. You had to guess. The ending was the best part -- because, finally, it was over.
The patch was not without problems either. A few people with the US version of Paradise reported having StarForce block them from playing after installing the UK patch, because the UK version of Paradise used StarForce while the US version used SecuROM.
