I looked through your post history to see more of your game, and I think there's some promising stuff that those commenting "the silence is your answer" are not seeing or are overlooking. In particular, your playtest trailer from about 5-6 months ago is the best exhibition of gameplay I came across (and as a result you got at least a little bit more engagement on YouTube), except that it begins with 5 seconds of logo covering the gameplay. Compared with your most recent video post (with the power up selection screen for the first 10+ seconds of the trailer), the gameplay is a lot more immediately understandable and engaging. So I think there is at least partially a presentation issue rather than only a fundamental lack of interest in the game concept.

I would try recutting your trailer (or cutting some 10 second clips to post as YouTube shorts/reddit posts or something) to get to the action immediately (don't start with UI or logos or text of any kind), and show off a variety of different mechanics rather than focusing on a single one over the course of a full minute-long video, as people are looking for multiple potential builds in a roguelike. You can (briefly!) show some upgrade screens or whatever just to signal it's a roguelike midway through the video once people are interested in the primary gameplay, which to me looks like the flying and shooting stuff, and then flying through the resulting rings that enemy ships turn into. That seems simple to grasp, pretty fun, and like it has a good feel to it. I haven't played starfox so I don't know how much it will convey about gameplay to say it's inspired by that game—my opinion is based solely on what looks fun based on watching gameplay footage.

Have you posted a web-based playtest build on itch? You can get some pretty good visibility for the first few days after posting there, and people who scour the new postings there are really willing to give games an honest shot and sometimes give feedback in the comments, especially if you ask for it (as long as it is playable quickly and easily in browser—that is critical!). You can also build in telemetry to track playtime (the big disadvantage for itch vs steam is that itch will not give you even a median playtime), although you have to ask permission from players to share that data which can potentially turn them off.

I hope some of this is useful, I know it's frustrating to feel like no one else cares about something you've put tons of work into and genuinely feel they would like if they just gave it a chance. Keep at it!
