It's a fun concept but it could really use some tweaking. At the beginning of the game I was scrambling to keep the clients happy, breeding and selling off monsters as fast as I could without any strategy. Later on in the game once I had better incubation and mating times, things got very repetitive trying to breed for better scores. In the end I had a group of level-95 monsters, but no way to improve them beyond that because nothing in the shop ever had high enough stats (even though I had hundreds of thousands of dollars money).
Scroll wheel controls zoom? I can't figure out how to scroll my mouse wheel without making it scroll the actual page too. Plus not everyone has mouses with wheels, and some people are playing on laptops.
There's too few checkpoints... You can't just play the game for a few minutes and then leave it. It's really fun, but I don't have that much time to commit to play.
