Very adorable graphics, lovely, with lively monochrome sceneries and very well made lineart. I also love how the more you walk, the more the scenery progresses into something more peaceful and calm, and how the character himself seems to enjoy himself the calmer his surroundings are. The music is also very nice and soothing, something to relax while listening to, too bad it stops whenever I stop walking, also, it's cool how every scenery's length is set such that they end as soon as the song ends. The presentation of this game is pleasant and soothing, very well made.
Gameplay is a bit weak, in my opinion. Sure, I like how the music goes on as the character does, and I also like how it goes in reverse when you press "back", but there's nearly no challenge at all, all the obstacles are easy to transpose, the difficulty hardly scales up, and the gameplay is just far too simplistic, without many features to keep it interesting.
All things considered, while the game is a bit lame when I think of it as a game, I have to admit it has a lot of charm as a piece of art, and that's not bad at all, and it brought a smile to my face :)
