Hi meryl, there haven't been any games like Green Moon released in the past year that I am aware of, but here are a few casual games that have been released that are relatively light on hidden object scenes and more adventure/puzzle:
Brink of Consciousness: The Lonely Hearts Murders
9: The Dark Side of Notre Dame
Reality Show: Fatal Shot (no hidden object scenes)
Nearwood
Margrave: The Blacksmith's Daughter
Surface: The Soaring City
Surface: The Pantheon
The Beast of Lycan Isle (no straight hidden object scenes that I can remember)
