From what I see, I don't think you'll be able to sell anything.

I would suggest you improve the colors on the page. The gray colors you're using now don't match the images or the tone of the game, and they give the impression that they're just generic template colors.

The main image looks okay, but it seems like a generic image created with AI, which isn't usually associated with high-quality, paid products.

Your game is a paid game, and based on the images, it seems like it's designed specifically for mobile devices. People don't usually pay for Android games unless there's a compelling reason, such as a well-known game or a genre that appeals to them. I don't see anything that makes your game stand out or that would entice someone to buy it.

PC gamers tend to avoid games designed for mobile, especially when the UI isn't even optimized for playing on a PC with a large monitor. So, from that perspective, it's very unlikely that anyone will be interested.

The videos you have aren't engaging. They don't show gameplay that makes me want to play.  You can see the character taking damage without knowing the source, and that's a very bad sign.

I want to be clear: I'm sure this isn't the kind of feedback you were hoping for. I'm sure you've put a lot of time and effort into your project, but unfortunately, what you're showing doesn't convey that. It looks very generic, and it's unlikely that anyone will pay for it.
