What an amazing idea! I have a few remarks. Playing it is annoying due to the camera (checkout a cinemachine 2d tutorial). I'd strongly suggest implementing some movement smoothing, like Brackeys does in his 2D character controller. The game's design is sound, but a better camera would make it much more enjoyable. (I'd love for you to check out my game; if you do, please let me know; I used movement smoothing and a Cinemachine 2D camera.)
