Great game, horrible execution. Typical freemium game greed. There will be levels that force you to use currency to progress. If you're on a win streak, you will suddenly get bad AI and get spammed with Red who will literally only target one area until you lose a life. Also I don't know what the obsession with obstacles that take two hits to win. If it wasn't for all of these things, this game would be so much better. But yet greed ruins another AB game, go figure.
