I would think not much. But I don't know much about your game. Looks like a puzzle game or platformer which are not very popular on steam. But it depends on how much time your willing to market your game and how much of a following you have.
when i looked at the marketing video they recomended roguelike deck builders which would give you the greatest chance of success. because it isnt over saturated with games. but there were other popular ones check youtube videos on marketing your game
