I have a bad habit of picking up NES games at nearly every used video game store I come across that still has some in stock, especially if it's a game that I don't already have (and the cost is less than $10). I picked up a copy of Fisher-Price: Perfect Fit around a year ago, but never took it out of the shrinkwrap to verify that it actually worked. I decided that since I was getting footage for a different unrelated video, that I'd fix that. What did I discover?
Not only does the thing work, but it's actually pretty terrible!
If you accidentally look at the built-in instructions, there's a ludicrous amount of text that I'm pretty sure will be completely ignored by the kids who are the age that this thing is targeted toward. Heck, I'm (allegedly) an adult, and I got bored reading the endless manual about seventy screens in.
All in all, it's pretty simple: match the shapes of the Fisher-Price toys that fall out of the chute on the left to the corresponding shadows on the right. Sometimes you have to flip them on their X or Y axis (or sometimes both!) to make them fit, and some of the toys that look symmetrical to the untrained eye aren't. That's about as challenging as this game gets.
If I had kids of an appropriate age, I'm not sure that I'd waste their time with this. But, then again, I wasted my own time with it, so I'm apparently not very good at taking my own advice.
