Lovely art style! Though it is way too dark for me to see. It would probably helps if the platforms are full block rather than a thin planks. Also, the music cold use a loop treatment so it doesn't end too abruptly. Overall, nice work!
I would love if you could review the art style in my game. It is a top-down shooter with pixelated art style. This is my first time ever making pixel art!
About the music i did it using BoscaCeoil and it was looped, but i dont know what happened with it ingame, got that harsh crack that Angelbait was talking about in his comment previously.
