Demake of Hollow Knight, quite interesting. Idk when is metroidvania month but this game could be good for that jam. Once you have experience building this game, i imagine you can create a much better game next time! Honestly keep up the good work! Also, as others have said, you can focus fewer elements so that the game is more polished, quality over quatity as people say, or you can focus on one element each jam, accumulate your experience, and create one great metroidvania with all the skills you've gained, just like a real-life metroidvania!
