Hey this was pretty cool! Super solid game made in the timeframe given.
I'm super focused on the music side of things, so having super cool music is always a bonus over the other silent games in the jam. Personally, I wished they looped better, or that the stages were shorter to compensate the length of the track.
Second, the stages are long. The lives mechanic is neat and keeps you in, but I had 15 sould by stage 3 and was getting bored due tot he stage length. I'd cut them in half even, nothing too crazy, but challenge theough padding the length isn't good game design imo.
However, this is a solid title with beautiful art and animations and a neat idea using the theme to drive the story. As others have said, some tactile sound effects (getting hit, objects getting closer so you know you're in danger etc.) would boost this up to a great game. You should be proud regardless, this was an awesome experience.
