Real artistic vision, one of those games where I was surprised to see it was done by a simple person only one person, SOLO. Usually those games have music/audio or gameplay not that developped. Here all sides are really good.
Music goes really well with the theme. Congratz on the mix/production side, I suck at it and I find yours really well done.
Same for SFX, you nailed them !! Lots of juice in the game.
Love the backgrounds, they bring so much flair. Your game and another one (TEN TEN) really showed me how much you can give a strong vibe with az relatively simple but "stylized" background.
There could be some little feedbacks to give if you want a full game from this, but honestly the result is already so good for a game jam, especially for a solodev, I want to say congratz more than anything !!
