Pretty obvious from the first time that you notice the "fade" (second object for me) that this is about her letting go of the memory of you and moving on. Epic, though.
I just wished the jumping was more linked to the high notes - especially in later levels. Was relaxing though - I'd like to see a level of association between the jumping and notes that lets you play with your eyes shut.
Oh, also: A few things you could do to add to the mini games... Running - Obstacles to jump through rather than just over.. Swimming, ones you can jump above OR swim under, and special ones where you have to press both? Flying... gaps in the middle also... Climbing is pretty good :) but more mazey? So more than one path? Some input in the races is probably too far for a "trainer" game.. But maybe it is too easy to keep the levels up.. Ghosts of multiplayers?
4/5 stars!
The concept of growing and seeing the world from a totally different perspective was awesome. The jumping was over-harsh, and the wings don't feel very real, though.
