Hey, I have published a new version. The vibration will be disabled together with music if you do not need it :) I decided to do not introduce a new button for it. The new vertion will be available for download approximately in 1 day. Hope you could give one more star because of this fix personally for you :) As for "add life" I did not understand.

Hey there! I tried to fix the behavior you experienced. Would be cool you could try again. The game itself is fun! You would enjoy it! And be sure, I have put a lot of effort into it :) It is a single developer game and I spent on it almost one year :) Not the main activities. Try it again, please!
