Yellows rating corner!
First of all a great concept!
using the scale of everything or outside of gensokyo to be used as a method of teaching for keine is neat in itself. and with yukaris flavor text to each scale comparission you cant help but smile. the lines feel very in character!
the visuals are insanely well done, the old paint style of japanese scrolls is just perfect for this and gives it even more the feeling of immersion.
as for the gameplay, in the end its just a picture with a slider to scroll in or out. while that is plenty enough to get the game across, it also makes it hard to give a proper rating to any gameplay.
the music is calm and makes reading the neat texts and admiring the artworks feel much more relaxing and not distracting.
Good Game!!
total Rating 4/5 happy Yellows!
