Wow, the game is really beautiful! The graphics and the music fits the game and the game concept is great.
I can imagine playing something like this as a full game, if there was more content.
I tried it multiple times but died every time, even though i had some HP left. I don't know, maybe it is a feature, not a bug. The idea that they sacrifice their lives and will never survive at the end. ;)
And one last thing, the music is beautiful. Shame that the looping music in the game has that pause between loops. It would be nice if the transition was seamless. Hope you know what I'm thinking.
Overall great relaxing game, nice work :)
