There is a problem

Purchased third area (top right quadrant) and everything was fine for a while (had many animals: wolves, panda, bison, etc). For some reason the area looks like it was wiped out by thanos with nothing left, and it is asking me to spend 250 gems on something that I already purchased (with the standard in game currency by the way) and all the animals in there are also gone (pandas and bison are quite expensive by the way!). Sooo... what gives? Give me back my progress. (Also the app has issues with crashing, some options don’t function 100% of the time, and I had to sell a gorilla because it was automatically sent to storage every time I tried to put her in an enclosure).

Promising but glitches a lot & gems are too hard to get free

The overall premise is neat, but the animals need constant upkeep. This requires you to either go into the app every 10-15 mins to clean & feed, or you need to hire a lot of staff. You can’t assign staff as you really need either, they have a preset pattern of plots they’ll cover which is frustrating because I don’t need them to cover support structures, just animal habitats. I have 10 staff members currently, but after manually assigning them a shift, 7 randomly went into rest mode. This happens a lot and my poor animals are left hungry & in dirty habitats. I’m hoping it doesn’t cause any to get sick. Once you get past the first few animals you need gems to hire experienced staff, buy more land and buy several animals. Gems are very hard to earn, so if you want to progress you have to pay actual money for them. The final frustration is it’s impossible to tell what habitat, and what size/temp an animal needs, until you try and place them. Even then it’s confusing sometimes because the fact card will sometimes say they prefer a certain size habitat or number of companions, but the hint they give you contradicts that. It would also be nice if you could zoom out to see the whole zoo at once, and if when you’re cleaning habitats the app didn’t zoom way in on you.

Fun, but glitchy

I found this game very fun, and I even tried downloading it on my iPad instead of phone to give it another try... but the glitches became too annoying. When there weren’t any glitches the game is fun and enjoyable. But eventually there was a long lag time between me touching the screen and the objects in the game moving, the front game stopped accumulating any income so there was nothing for me to collect, the “Claim Reward” button would show an error sign and I wasn’t able to claim any rewards for completing tasks or benchmarks, and if you don’t want to spend real money on gems then the ratio of staff to habitats is unrealistic. Every time I returned, even with all 6 staff members working, I would have messy habitats and unhappy animals. The only way to buy staff after the first 6 are through gems which cost actual money and are hard to come by through just playing the game...especially since as I mentioned earlier the “Claim Reward” button wasn’t working and neither was the “Collect” coins button for the in-game currency. Altogether, along with the glitches makes this game more frustrating than fun. It’s really sad because I think it’s a great game if it worked appropriately.
