It doesn't work at all :( When getting your first cat, that's all that works. The timer starts from 14 minutes, then jumps to 3 hours, and the ads do not work. And when you exit the app and come back, the first cat is gone. (And from what I saw, there was no way to access anything except the first room and the window. Also you could buy both toys in the garden even with 0 coins.)
We just released a new version (CatTower_0.3.1_29.apk) Please let us know if this new version solves the issues. It is recommended that you uninstall first and then install the game again.
Please note that the Google Playstore might take a couple of hours to show this new version.
Thanks again for your feedback <3
