The narrative worked really well and was a nice way to incorporate the theme, it might have been nice to use the same idea in terms of gameplay (eg "failure is fine" would come after landing on spikes or something like that.) The range of different graphical elements were also a nice touch considering the narrative as well as the animations ins some of the levels really helped to make the game feel more alive. There were some nice touches of polish too like the fading scene transitions and the way in which the credits start at the end.
The narrative was quite inspirational, however on a gameplay level I feel like there could maybe be more to do, even if its something like collectible or some more platforming with dynamic platforms. Some sound effects would have also added to the experience.
Overall, I really enjoyed playing and I would definitely recommend playing this game: has the best narrative use so far that I've seen!
