Usually you wouldn't think of a game with ghosts as being cute, but the ghosts in Ghost Mania remind me more of Casper or Slimer than anything really scary. Given that this is a puzzle game, cute ghosts make it a bit more family friendly. There's no reason that people and children of any age shouldn't play this game, especially since the graphics should appeal to anyone. Once you get them unlocked, there are quite a few choices for backgrounds that you can choose from. Personally, I didn't really notice the backgrounds after the game started. My one complaint with Ghost Mania is the choice of colors for the blocks. You start out working with pink, blue, green, and light grey blocks. This would be fine if the other blocks in the puzzle mode weren't dark grey. Sometimes, if I wasn't paying close attention, I'd get the pieces mixed up. It would have been nice if that light grey had been something more distinguishable.
I did really enjoy the background music. It's peppy and upbeat, which always works well in any puzzle game. Plus, when you're getting closer to the top (and nearer to dying), the music speeds up letting you know that you're in trouble, just in case you hadn't noticed it on the screen already. As far as speaking, well you're not going to get any voice acting, but you do get a very amusing yet sinister laughter when you release the ghosts. Turn off the lights and in a silent house, it'll make your skin crawl just a bit, in a good way.
