In spite of ads that must be closed multiple times to get back to the game, I enjoyed it for a week. But now I must purchase to progress. For the last 4 days, I play all the lives given, but complete one round & fail the others; not enough to progress, only to be frustrated. Thanks but no thanks. I'll uninstall, move on. Developers forget this--it has to remain FUN if you're to retain players--and that means reasonable progress without paying. Isn't that why we endure the ads anyway? Bad move...
