The spawners are reacting at "light speed" so that it is virtually impossible to get any where with this level. This seems to be happening with mobile devices, i.e.: i-pads and phones. From what I have read on this chat forum, as well as others, this is not an isolated problem. I usually have no big problems completing levels, but even using all my boosters, it is an epic failure. Don't check this problem using a desk or laptop..very different. Otherwise I will delete this King game, and look elsewhere.
