The game is reasonably fun... very frustrating because sometimes the physics seem to make it unwinnable, but I could get over that. I was also miffed by the fact that the game encourages you to spend coins on “upgrades”, but all the “upgrades” do is to add animated clutter to the game board, making game play more frustrating by obscuring what you’re trying to focus on, but no more rewarding. I worked around this by deleting the game & reinstalling to get rid of all the “upgrades”, and avoiding them thereafter.
What I can’t get over is the fact that the ads are just too frequent, too long, too hard to dismiss, and just too unpleasant to watch... they made the gameplay so unenjoyable, that I had to decide to either delete the game, or pay to remove the ads. For me, the developer’s choice to include such intrusive ads in the first place, biased me against them... and the best choice was to delete the game. Boo.
I would certainly tolerate the ads if they were a little less annoying, or if the gameplay were a little more fun. I’d even pay to remove them if I thought doing so would result in a good user experience. But as things are, I feel like the game would STILL be lacking, even without the ads.
