Very nice game! Few things, which you can change/add:

1. Some music! 
2. First level is too long and boring :)
3. Back button in menu is not closing game (I’m using android device).

Thanks for your feedback.   :D

:D

:D

I agree with makalele. This game could have mass appeal if the levels could be completed faster. Go to fiverr.com if you really want game music. Also, the back button should always grant the option to ‘escape’ the app as quickly as the user desires, IMO.
