i really love the graphics, i just dont think 2d and a rhythm game work together? the theme is kind of obscure, like you wanted to make your own game and just used the narrative as a way to incorporate it? Personally the rhythm movement makes the game too slow, if it was a bit faster and the shotgun had a crit chance if you timed it right, maybe? But the puzzles were also just generic and simple and repetitive very fast
its a good idea though, it just needs a lot of polish and development
