Playing on android, finishing level 14 just looped me back to play 14 again. The empty bottles at the top suggest there is a 15th level. Not sure if it is a bug or waiting for further updates.
I enjoyed the beginning of the game, but it is becoming a drag towards the end. The gameplay doesn't evolve in any way, and "harder" seems to just be "catch even more girls than last time", which is taking quite a long time at level 14!
Nice game though, thanks!
