As you said for the price tag it wasn't really value for money in terms of gameplay length, but it does show a new side of Puzzle/Adventure type games which is good.
I think within half way I soon realized yeah I know what will happen at the end, there was many hints too early about it, "Ethan wrote to me" and "Ethan said that..."
The only puzzle that gave me a little time to think was the burned out house, but with a bit of logic it didn't take long. Wish the other puzzles where a bit more difficult.
