I used to rate this game at 5 stars, it was generally really good outside of the fact that the energy system can be very limiting but now they've implemented forced ads. I was willing to watch ads for rewards but you can only do that every 12 hours. Maybe instead of forcing me to watch ads just allow more ads for rewards. My review will stay at 2 stars until this is changed and if it's not I will probably quit very soon.

Great work there DEVs, I was surprised by the art, the game mechanic, and the detailed options.. But obviously there's a major issue that make me take one star from review it's the water, 9 hours is a lot of waiting time, no option to get some water with game CACH or gold coin (except 50 coins bundle). The second removed star gos to the expensive Pet upgrade cost and the shelter building, clearly needs some balance between the cost & what the building give us back, specially on water section...

New UI (February 2023) is a huge step backward. Poor contrast, poor accessibility, and difficult to navigate compared to before. And no, the dark theme doesn't help, the problem is that the buttons are too large, blocky, and low contrast to easily find what you are looking for in each screen, making an otherwise decent game into a painful experience.
