True sacrifice and negative progression are two ideas rarely exploited in video game, and I'm quite delighted to see your version of them, even though you're not the first to exploit them. The music brings a lot to your game, as well as the atmosphere. The platforming aspect is basic, but the message is beautifully sent. The quote and the little guy are touching. Seeing him losing his wings, his legs and finally disappearing into -I don't know, void? transcendence?- is nicely done. I regret that some jumps on the platforms result in passing through them, provoking quick irritation. Was it intentional? It is not a big deal anyway, as you can persevere and reach your goal -isn't it the idea, anyway? But overall, the idea and how you displayed it was quite interesting. Looking forward to hearing more from you!
