As a black and white enjoyer, loved the aesthetic. There's a great idea in using these shadow 2d objects in a 3d space. A bit less red could actually add to the atmosphere, in my opinion, but it's a minor impression. The choice of song was pretty good, it isn't synced up to the action through code, but it has the rhythm of the action of your game, so sometimes the sound and the gameplay match up so well it actually feels like your inputs are shaping the music.
A small garden of great ideas and execution, I adored it.
