UFO Dad is visually appealing in that it is filled with bright colors and an amusing backdrop. The characters themselves are large on the screen and unique so that each of the four members of the family being abducted is easily distinguishable. This means that, if you happen to be jumping into a game that you've paused some time ago, you should be able to tell immediately which character and traits you are in the middle of controlling. Given that the characters have slight differences in their range of movement and abilities, this can be handy. Then again, the strategies for the different characters only vary a little, so you shouldn't get yourself in too deep of a pickle if you forget which character can do which ability.
UFO Dad's music has a classic arcade feel to it and has a steady enough beat to keep you going and pushing forward, but it isn't long before you've heard all it has to offer, and much like the rest of the game, it gets a bit repetitive. While nice, there isn't much of a gameplay experience difference if you simply turn off the music and continue playing, which is good for a mobile game.
