Good concept game! Sadly it crashes frequently, has problems maintaining wifi connection, often cannot load ads, often failed to give a bonus after an ad, and now will not load its own update. I tried this game to get a bonus in another game. The failures mean I will not receive that bonus. It has been little more than an annoyance. Good bye! Update: I said "good bye" sir! (Couldnt resist)

Fun like I would expect an idle game to be, however, right after 2 or 3 ads you click on to play when it's time to get back to the game, the game screen goes black frozen for about 7 to 12 seconds and then just closes. When I open it back up it doesn't give me the credit that I earned to watch the video. I struggled through it for an hour because I liked the game but I'm over it now. Badly rated, unstalled and on to the next. Shame. I usually play these for days. 🗑

Definitely WAY BETTER than any other games of this type that I've played! The screen isn't over flowing with ad watch prompts and the graphics are cute. The sound is a touch rough, as it sounds like the speaker on my phone is blown out. (Playing on a phone that's only a month old and hasn't been used much yet). Other than the sound issue I'm having, EXCELLENT AND CUTE GAME!
