Its ok. It is a game of patience and positivity. Try thinking of other ways to solve problems. Like in this case you could have advertised it in the release announcements. Just be patient.

You published your game less than a week ago. It takes time, and promotion work.

It looks quite nicely presented and appealling. It might just be that very few people are seeing it in the first place. You might need to do publicity elsewhere- like the social media stuff that everyone hates. A browser build might help you get more plays. If you do this, consider releasing on Newgrounds too.

Take advantage of the feedback section of itch forums. Other creators can give feedback on your game's appeal and even play it for feedback

When I checked out your game's page I assumed it was a puzzle or adventure game by reading the tagline and story. But when I watched the trailer it made me think it was a lot more like Hollow Knight (the effects looked great by the way) I think the tagline and summary of your game could have better pointed to being a 'atmospheric 2D adventure' to give the game more kick and appeal. The story seemed fine but was very vague as to why I should play it when you could boast about it being a dark, mysterious 2D fighting game with bosses

If your goal was to make a Hollow Knight inspired game (just presuming here, sorry if I am wrong) then research how fans refer to their  game such as using a souls-like or hollow-like style game in your tag to draw relevant fans in. Personally 'whimsical game about a cute character called "Chi". ' sounds generic to me but a 'atmospheric 2D hack n' slash inspired by Hollow Knight' will get more people interested if the genre or style of game resonates with them. 

Take that with a grain of salt. Marketing is hard and I am not an expert - hope you get more traffic though
