My inner OSU player loved this. It took a while to get the hang of judging when the shadow hit the the monsters because it doesn't contrast as well as it could but once I had that down I got to experience a very well mapped level! The timings were on point making the level feel really awesome to play! Menus felt nice to interact with generally, just would have loved to have a little more feedback when interacting with buttons and shooting (especially in terms of SFX).
Here's the part where I plug my own game, it would be really awesome if you gave it a play!
