Despite its appearance, this is not a casual game. It has gameplay rules that are a lot more complicated than you would think, though the in-game documentation is not always clear on everything.
For example, beetle-infested coins will not exert the effects that the coins would otherwise have if they are not infested. You can learn this first-hand in level 32.
