Easy but good game. Using elimination method it was no challenge

It was a good game and easy.
I would like to suggest to add more levels to make the game challenging and to add more music.

Pretty easy, but makes you look really hard on some of them :)
I like it, but make add some music as well?

funny how after the 4th level i didnt have to look at the original anymore.
You only have to notice the differences in the black ones, key features always appear in 4 out of 5 so i used exclusion. Otherwise nothing new but what it does it does okay.
3/5

a simple puzzle game that would be great for kids & could be challenging for some adults.
Good work on an old classic =)
