I haven't played your game, so I'm going to base my critique on the video and itch.io page.
Your game has a very early 2000s shareware vibe, and you could stand to lean into that a bit more, look up promotional copy from games of the time for ideas maybe.
Also, all the trailer tells me about your game is that it's a twin stick shooter. Consider your game next to others of the same genre. What does Maze Quore do better than Nuclear Throne or Thoth? Or like, Smash TV? Make the video about those things.
Also also, temper your expectations. More videogames were made last year than between 2006 and 2014. The audience is spread a lot thinner than it used to be, and a lot of finding your players is luck and hustle. Make yourself prolific, release a lot of small projects, or collaborate with people more popular than you.
I hope that helps.
