Played a few of these now...
Rare Breeds: Petunias is amusing for a while. I tried to create the most warped flowers that I could and successfully engineered a stick, a blob, and something that looked like vomit.
Submachine seemed well put together, but it is too small to see the details clearly!
[Together] looked lovely, but catching the hearts felt like hard work after the first couple. In fact I never caught the 5th and quit the game!
Zoo Director is yuk! It really makes me appreciate all the Zoo Tycoons of this world!
