This is a great recommendation for Halloween; I too enjoyed the game very much.
Being as you have become a Nevosoft fan, have you ever tried Mushroom Age?
It's quite an old game now, but it's very quirky. Let's just say that it gives new meaning to the word "strange."
It was very popular with players when it was first released.
Another one worthy of mention is The Emptiness.
Lots of players enjoyed it here and it's quite different from the usual fare. This one does not come from Nevosoft, but it would make a nice Halloween game as well. Dreamland
also has the Nevosoft name on it. Again, very popular with players. Quite a few puzzles and mini-games, as I recall (as well as some hidden object scenes).
