It is an unique way to play a zoo tycoon like game but isn't for everyone. Instead of money, you earn popularity points to spend on upgrading the park. All of the animals besides the beginning one must be earned through research. Barebones, it is a zoo park--no multiple scenarios and limited amount of challenges to achieve.
If you are looking for wonderful graphics, look else where. But it does have its own bit of charm, if you ignore the slightly annoying two-thirds angle. It feels more like it was designed to be a mobile game that was changed half-way through the production process.
The big problems I have with it is my animals get sick soo easily, even if their habitats are clean. And the breeding program is annoying at best, with the first animals you buy will most likely never actually have any children before they become too old to do so.
It has enough interest to keep me going for awhile, creating multiple parks. And for its price, it works. However, it wouldn't have been worth it if it was more expensive.
