Relaxing/Cool Game

Maybe you've seen this before, I don't know. It's pretty simple but I find the music and imagery relaxing. It does get a little weird in some levels though.

It's kind of hard to find all of the differences, but it is a pretty cool and relaxing game.

It pissed me off because I couldn't find them all, started clicking all over the screen and my stress level went up.

I love puzzles!
