I like it :D It's a good game =D Very challenging ! :)
Just don't give upp on the game if oyu can't make it, just think backwards and you should be able to do it =D
True, don't give up. Keep trying various patterns and you'll make it in the end. Everyone says 16 is the hardest and I agree. Think I tried about 30 different patterns before I made it, so don't give up! :)
