Very good game! I think I found every wallpaper, but I don't know if I have every effect... Without counting the normal one, I got 5. Also, I can't get from the snow world to anywhere, is there another path to find?
Thanks for playing, glad you enjoyed! There are currently 6 effects in the game so there should be one you haven't found yet laying around. The snow world currently doesn't connect to anywhere or have any effects in it, if that helps.
