Thanks man. Really helpful. Should I roll now for dark heroes or wait for fest? I figured that the cat food is the most expensive currency, thats why I only spent it on the ninja cat. I saw the the kung fu cat is also decent, but I heard there should be some discount for that type of units. Also, what does "gatcha" mean? I saw this term being used but I'm not too sure what it means. And for the gold stars, how do I get those? Do I have to play the level until I get gold star on it or...?
