What an interesting lot of reactions! Everything from "I uninstalled it" to "Can't wait for a sequel"
My take: I like it enough to go looking for the Sacred heart; hadn't heard of that one. Why do I like it? First, it has a story line that more or less holds together, and it has different puzzles the likes of which I have not seen before. Not so darn many keys to find either. (Keys are boring, aren't they?)
Good voice acting. I know it costs a lot of money to include real actors in a game, but it's worth it when done well. Helps the player connect.
Oops gotta go; more later maybe -
