I'd give this game 4 stars! Some of the levels are really difficult for me. sometimes Tata would not throw a bubble until the dandilion moves higher and higher. It may be a glitch but Im fine with that. Overall, I love the game! I like the challenges. I hope you guys add a feature where you can watch an ad for 1 ruby. I also find the game pretty adorable :D

It's so entertaining you forget time. Great job! . . Edit: After playing the game for some time, the game crashes and does not save the progress. This leads to loss of churros (life) and not completing the stage. It takes a while before you earn 1 churros and you only have a max of 5 each visit (unless you earn one or buy while playing). I understand the game is new & prone to bugs like this but if this could be looked into by the developer, that would be great.

i did really enjoy the game, but i didn't log on to play the last few weeks and now when i go on it logged out my account (was using a guest bc i don't have line) and now i have to start the whole game over. id played over 200 levels, had good characters, and had spent a bit of money on in game things. and now it's all gone. i want to play again but also, it's kind of disheartening to lose that progress. 4 stars for the fun - loses 1 star for my losses
