Why in the world does each monster have a secret "like"? It's not fun and doesn't add anything enjoyable to the game at all. It simply makes island arranging frustrating.
And yes, I know there is a wiki for this game. I'm using it now. That doesn't change the fun-ness (or lack thereof) of the hidden "likes" system.
Either way, through trial and error or by referencing the wiki, making the players figure out what the last "like" for each monster just feels like a poor design choice to me. I may be alone, but there it is.
Let me follow that up by saying I love everything else about this game! I only have that one gripe, and have really enjoyed every other aspect about this game. I used to really love Dragonvale, but grew tired of it after a while. My Singing Monsters is so much more enjoyable to load up, simply because of the music aspect of it. Even my 6 year old daughter and 11 month old son love it!
And on that note, I would like to extend a personal "THANK YOU!!!" to the developers of this game. My son loves this game so much that even the initial load up screen (the black screen with the furcorn at the bottom) can instantly calm even his worst cranky cry-fests. It's been such a godsend during his teething times. I'll often sit him in my lap, load up the game, and put it in view mode and he'll just sit there giggling away as he touches each little monster. So yeah, out of all the things we use to calm down a cranky baby, My Singing Monsters has worked wonders and has become my go-to tool for quick baby soothing.
