Just wanted to check some match-3 games and stumbled upon this one. Good game but some game mechanics are odd. Like the metal tubes. If I combine the bomb and the arrow thing to make 3 arrows go both up/down and sideways, when they go across the metal tubes the tubes only retract as if they were hit by one arrow. There are other things like that but that's the most obvious. Otherwise it's an okay game without too much of annoying ads so it's definitely a plus.
