Decent experience, lots of ads which happens for mobile games like this, and easy to get all the items. Level 190 a stone falls the second the game starts and blasts tnt next to you, giving you know time to react before you just fail the mission. Not even enough time to change weapon or go back to a previous level. Then the game over screen didn't show for retry or skipping the bad level. I think level ideas ran out before 200 and needed a barrier to keep players from going further.
