Any chance for what? I dislike platformers, I dislike (extreme) pixel graphics, I might be quite far from your intended target audience.
But after looking at your gamejolt page, I can tell, you should definitivly work on the first few minutes of the game. People might give up, before seeing all the cool stuff. Imagine someone playing this for the first time. They do not know what is to come. People need to get invested, before you can punish them. And do not count on people watching any videos linked on different platforms. If it ain't an animated gif onpage, people like me will not see it.
There are near a million games on itch. People trying out games will give you a quick glance, maybe a minute of playtime if it is web and then move on if they disliked it.
What put me off at the beginning was the controls and especially the collision detection. That seems to be too sensitive. I am dead and on the condescending screen, even before I touch the enemy. Oh and on second try, it would have been nice to know that there is triple jump. Or that the space key also is jump. But attack on return is still awkard for my hands.
