Don't pay for extra lives etc. I really enjoyed this game, it's different to your usual match 3 games. However, once you pay for power-ups, the levels become virtually impossible to complete. I played the same level dozens of times, in several different levels but still unable to complete, with just one tile, gem, bird etc remaining, virtually every time I played those levels and an offer of 50% off power-ups,each time. Wish I hadn't paid out. Not enjoyable any more. Uninstalled it
