Fun, but annoying.

Some levels are incredibly difficult and offer a decent challenge. But whenever you run out of lives to keep playing, the game makes you spend money for more lives which will last 5 minutes tops or watch a crappy video for 10 lives which last no time at all. Without the life system it would be infinitely more fun, and you wouldnt feel like your wasting your time with videos and purchases and forget what your even doing in the app.
