Definitely has potential, I think! I kinda like the aesthetic and overall vibe. I agree with Anqareliouth about the game being too hard, but I personally don't think this is an issue because of the music, instead I feel like the difficulty really arises from the game's controls not being responsive enough to match the speed and reaction time the game demands of you. Enemies react to your presence very quickly, but whether you survive your encounter with them is basically already decided when they start moving; if you dashed past, but dashed a half-second too late before they awaken, you die. Things like acceleration for movement are great for adding a feeling of weight, but in a game where things happen so fast, it just gets in the way of being able to respond quickly.
Still, not bad!
